Benchmarking Performance: Benefits of PCIe NVMe SSDs for Client WorkloadsSamsung Business USA
The transition from Serial ATA (SATA ) to Peripheral Component Interconnect Express (PCIe) interface and Non-Volatile Memory Express (NVMe) protocol is taking client storage to a new level. This white paper discusses the benefits that PCIe NVMe SSDs, such as Samsung’s 950 PRO, bring to client PC users. Client PC workloads are not always well understood in the industry, since common benchmarking utilities tend to focus on measuring maximum performance rather than performance under typical PC usage. This white paper looks at actual IO traces of PC workloads to better understand how client SSDs should be benchmarked, and also tests the 950 PRO against other Samsung SSDs to show how PCIe and NVMe improve IO performance in tests that represent real-world IO activity.

The document discusses the genetic, gonadal, and structural bases for determining sex. Genetically, females are XX and males are XY. The Y chromosome contains the SRY gene which causes testes to develop in males by week 7 in utero. The testes then secrete testosterone and other hormones which cause the Wolffian ducts to form male structures and the Mullerian ducts to degrade, leading to female internal structure development. In the absence of these male sex hormones, the default female developmental path occurs.

Hardware refers to all of the physical parts of a computer system. F.pdfanjaniar7gallery
The document provides information about various hardware components of a computer system, including RAM, hard drives, graphics systems, and installing/upgrading these components. RAM is temporary memory that improves performance when more is installed. Hard drives store long-term data, and upgrading to a larger or solid state drive can speed up a computer. Graphics systems handle visual output, and a dedicated graphics card provides better performance for gaming and video editing than integrated graphics. Installing or upgrading RAM, graphics cards, and hard drives involves opening the computer case, inserting/connecting the new component, and ensuring proper installation through software.
Partition alignment dramatically increases system performance by properly aligning partitions with the physical sector size of storage devices like hard drives and SSDs. When partitions are misaligned, it causes redundant read/write operations that degrade performance and reduce hardware lifespan. The Paragon Alignment Tool helps solve this issue by easily moving partitions to be aligned with physical sector boundaries, providing up to a 2x boost in file system operations on 4K hard drives and extending the lifetime of SSDs. Misaligned partitions can also negatively impact performance in virtual environments and storage area network (SAN) and RAID configurations.

This is part 1 in a series of talks covering Padawan Monica Beckwith’s hands-on practical experience over the last two decades. Monica, who has trained with many Knights and a few Masters, will cover what it means to be sympathetic to the underlying hardware in Scaling Up and Scaling Out scenarios. In addition, she will share examples to put cloud performance into perspective.
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

Essentials of Automations: Exploring Attributes & Automation ParametersSafe Software
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

Overview
This paper details the purpose and benefits of a ground-breaking technology alliance between
NAND Flash hardware leader Apacer Technology Inc, and storage performance technology
innovator Diskeeper Corporation.
The Problem
Solid State Drives (SSD) have several issues that come into play when used as the primary
storage medium in place of traditional magnetic Hard Disk Drives (HDD); specifically regarding
the operating system’s logical file system. To date, file systems have been designed under the
pretext of HDDs, and do not properly account for new NAND Flash / SSD technology.
This leads to issues that negatively impact mass market adoption of NAND Flash memory into
the consumer, small/medium businesses, and enterprise markets where legacy file systems,
designed for HDDs, will dominate the landscape for many years.
Problem Analysis
The principle issue is write speed degradation due to free space fragmentation. Small free
spaces scattered throughout a volume at the logical level cause the file system to write a file
in fragments to those small free spaces. This will degrade write performance as much as 80%
to that solid state storage device. Fragmented free space forces the writing of blocks that are
not advantageous to write or erase block boundaries, even if the application software would
otherwise use large buffers.
Diskeeper Corporation has tested many current SSDs, from many manufacturers for file
write speed degradation as a function of free space fragmentation. NTFS, the most common
Windows® file system by far, is shown to fragment free space rather aggressively over a few
months and then grows slowly thereafter when not maintained (figure 1).

Write performance decreases proportionately as free space fragmentation increases. The graph
below (Figure 2) shows the resultant 80% write speed reduction on a variety of drives due to
this effect. The test included copying a 1GB file on to an SSD with fragmented free space. The
graph axis depicts the I/O write throughput in megabytes per second (MB/s) in relation to the
number of file fragments the file is forced to be written in due to non-contiguous free space
clusters. While a brand new SSD device may offer write performance in the 80 MB/s range to
start, after a few weeks of use, performance will quickly deteriorate to 35 MB/s. Over the span
of a few months, write speed becomes painstakingly slow at an abysmal 10 MB /s.

Number of Resulting File Fragments
Figure 2: Write I/O throughput degredation due to fragmented free space.
It is important to note that the performance loss due to fragmented free space affects all
NAND Flash memory drives shipping today. The issue is not relegated to one specific vendor
or other. The results depicted in Figure 2, for example, are non-Apacer devices.
The Software Solution: HyperFast™
As described, the issue originates with how an operating system interacts with the storage
hardware. The nature of modern operating systems, their regular updates, and the applications
which run on them, have been designed with no forethought to the effect of free space
fragmentation and its unique impact on SSD NAND flash. While moderately immune to effects
on read-based file fragmentation, NAND flash is extremely susceptible, based on the empirical
evidence, to write speed degradation when the free space is moderately to heavily fragmented.
HyperFast delivers automatic maintenance of the file system, keeping a low level of free space
fragmentation through specific optimization techniques which preemptively force the file
system to write sequentially rather than randomly.
This technology dramatically improves SSD performance. Specific tests were performed to
demonstrate the improvement. The test depicts an environment with free space fragmentation
in a range as might be expected from about 6 months of typical system use.

NAND flash drives have limited erase-write cycles. This fact mandates that any optimization
program that may seek to increase performance cannot acceptably do so at the expense of
wearing out the drive faster. A tool, specially provided to Apacer, from BinarySense Inc. called
SSDLife™, was used to measure the average erase-write activity on the Apacer SSD device
from various actions.

Figure 5: Cumulative Erase activity on Apacer 8GB PATA SSD as measured by SSDlife software.
Starting from a freshly Windows’ formatted drive (stage 1), fragmenting the free space (stage 2)
generates a score of 10 from SSDLife’s proprietary scoring system. Then running the HDBench
program (stage 3), which creates and reads files to measure hardware performance, generated
a count of 4. A reformat (stage 4) incurred no change. A second run of the free space
fragmentation routine (stage 5) averaged an Erase count of 9. HyperFast was then run (stage
6) to optimize the SSD. It created Erase activity at an average count of 4 (identical to HDBench
in stage 3). HDBench was then run on the optimized SSD (stage 7), and this time only incurred
an average Erase count of 1.
This test indicates that, while the SSD optimization techniques employed by HyperFast do
incur the occasional increase in erase-write activity, the result of its operation reduces the
erase write activity of typical day to day use of the SSD. The net result of using HyperFast will
be less erase-write activity on the Flash drive, thereby increasing its longevity.
It should also be noted that in the test case above, the effort required from HyperFast (in
stage 6) was the reparation of many months worth of accumulated free space fragmentation.
The intelligent algorithms employed by HyperFast are designed to optimize the drive’s
performance and maximize its useful life.

Summary
With typical system use, the out of the box performance of computer systems shipping with
solid state storage devices will not be maintained. This is not due to quality or design of the
hardware, but rather the fact that inherent attributes of file systems will manifest over time.
Fragmentation, in this case primarily of free space, is a natural side effect that will occur and
accumulate over time with all file systems. As free space becomes increasingly fragmented,
performance will suffer proportionately. This leads to increased, excess write activity on the
NAND Flash device, diminishing the device’s longevity and reducing its performance dramatically,
especially with write speed.
Apacer NAND Flash devices with HyperFast will out perform competitive solutions. As a
result of this revolutionary technology alliance, users of Apacer solutions will enjoy greater
performance which will be maintained for the full, extended life of the storage device.
