MySQL is one of the most flexible relational databases to work with for adding, accessing and managing content in a database, but at times it can be unpredictable and painfully slow. This can hamper your work and can bring your applications to a screeching halt. This quick tips will help you avoid some of the mistakes and make your MySQL perform better.

3. What is MySQL
MySQL is one of the most flexible relational databases to work with for
adding, accessing and managing content in a database, but at times it can
be unpredictable and painfully slow. This can hamper your work and can
bring your applications to a screeching halt.
At times the common mistakes underlie the MySQL performance. To
overcome this problem and to ensure your MySQL server moves along at
top speed, providing stable and consistent performance, it is important to
eliminate these mistakes by using simple yet effective performance tuning
method.

4. Tip No.1: Define server workload
Profiling your workload will give you an opportunity to expose the most
expensive queries so that you can fine tune it further. And the best way to
profile your workload is through the use of tool such as MySQL Enterprise
Monitor's query analyzer or the pt-query-digest from the Percona Toolkit.
This tool will capture server queries and shows you most expensive and
time-consuming tasks. This way you can take most informed decision.

5. Tip No.2: Understand
CPU, Memory, Disk, and Network
If any of the four fundamental resources like CPU, Memory, Disk, and
Network is underpowered or weak or there is an overload of some sort
then it will severely affect the database performance. Hence choosing a
right hardware is very important. At times companies buy faster processor
or CPU but will starve the system for Memory thereby severely affecting
the MySQL performance. Care should be taken to check the performance
of the four resources from time-to-time and troubleshoot if you come
across any issues.

6. Tip No.3: Remove unused indexes
Indexes which are not used for long and are redundant must be removed
so as to improve the performance of MySQL. Too many indexes decreases
the performance. If you have more IO the you need more CPUspace to
update all index. Also remove the same prefix indexes.

7. Tip no 4: Do not concentrate too much on
configuration
Many Database Administrator spend their time configuring and tweaking
database system. Though it is good at times but overdoing can prove
damaging. It is important to know everything about your MySQL and
change settings only it is needed. In most cases, you can get 95 percent of
the server's peak performance by setting about 10 options correctly.

8. Tip No 5: Monitor the database
A monitoring tool is a Database Administrator best buddy. It can be used
in two ways – to capture metrics and to get notification. Hence if someday
you are encountered with some issue you know where to check for the
problem or what exactly is causing the particular problem. But getting too
many notification or alert like buffer hit ratio or the number of temporary
tables can be overwhelming.
When you get an alert with a specific actionable problem then this type of
notification helps you to offer a solution. If you get a notification for a
server that doesn’t respond to a connection attempt then it requires
instant troubleshooting.
