4. Introduction

5. Before we start to optimize your website’s
performance, it’s essential to set a goal for
where you want it to be. That can be
difficult for you if you’re not aware of what
acceptable page speed is.
As per the Google’s latest guidelines, the
faster your website loads, the higher the
chances are to achieve favourble results,
and improve your conversion rate.
That’s the main reason why website
optimization is the most crucial aspect for
any website owner. Here we’re going to
measure your website performance and the
tips that help increase website loading
speed by optimizing your website’s back-
end and front-end because front-end issues
are equally important as back-end.
So, let’s get started!

6. Facing
Website
Performance
Issues?

7. A website with good performance
represents a brand and its image. It is
essential to keep an eye on your website
performance as it doesn’t take much time to
have a better UI/UX. Every user expects
their website to be best and fast.
Sometimes, the website does not work
correctly, and you face issues that may
impact your business and your activities.
Out of 20, 17 digital product owners believe
that there might be back-end issues that
cause trouble to the website performance.
Well, they are undoubtedly right. Almost
60% to 70% is the possibility that there
could be Back-end issues. However, when it
comes to improve your website
performance, do you know it could be slow
down because of a front-end issue as well?
Some of you will agree, whereas some of
you won’t.

8. According to Steve Souders, 80% of the
average page load times occur after the
markup is completely downloaded. For your
users, a 50% speedup in your front-end
code is going to mean a lot more to them
than a 50% speedup in your back-end code.

10. The back-end issues, as mentioned above,
are not the ones that can hamper. There
could be front-end issues as well. Because of
these common front-end issues, people
won’t even give your application a second
thought if it is not visually appealing.
Nobody will care if your back-end is fast if
your front-end is not convincing. Moreover,
solving front-end issues won’t be that much
more critical than it is in the back-end. So,
let’s have a look at common front-end
issues.
Only Back-end Issues?
What if There are Front-
end Issues Which are
Affecting your Website
Performance.

11. 1. Lazy loading
2. Large size images
3. Unused CSS
4. Brotli and Gzip Compression
These are the common front-end issues
people come across, and that hampers the
website performance for sure.Now, you
might be wondering. We already know
these common issues, and some of you
might know how to solve them as well. But
let me tell you that there is always a
learning curve. Let’s educate each other
about the issues and how to get rid of them
with better solutions.

12. You must be wondering if there is any one-
stop solution that can solve back end and
front-end problems both. And guess what?
A full-stack web developer is a one-stop
solution and knows how to get rid of them
with better solutions.
A full-stack web developer can be a one-
stop solution to solve the front-end as well
as back-end issues.

13. What is a Full
Stack
Developer?

14. To put it in a nutshell, a full stack developer
meaning a well-versed programmer who
has the expertise of both ends to offer a
smooth user experience: front-end and
back-end development. A full-stack
developer can jump from one part of the
application to another without significant
overload. This is a huge advantage when
planning forward or when designing new
features. That’s why more and more
developer wants to become a full-stack
developer in 2020.
A full-stack developer can efficiently work
on both front-end and back-end
technologies like;

15. Front-end: Angular, Vue, and React
Back-end: ROR, Laravel, .NET, PHP, Python,
Golang, and many more.
A full-stack developer is the one who is
well-versed with more than one technology
in a project and came up with great
solutions no matter what scale of
application it is.

17. The N+1 query intricacy frequently happens
when any queries are assigned to associated
fields in your database instead of printing
one compound SQL query, including all the
reports which are to be regained. Using
eager loading, all associated questions are
requested with a single entity instead of
multiple queries that may slow down your
application’s performance.
1. The N+1 Query
Problem
2. Database
Optimization
Database optimization plays a significantly
vital role in improving your website
performance. Sometimes unoptimized
databases may slow down your
performance and denormalize your
database.

18. Normalizing a Database
Normalizing your database is a logical outcome
when designing a relational database, but some
developers still decline this process at times.
Optimizing databases reduces the amount of
space that a database requires and organizes
your data to improve website performance.
Database Indexes
A common issue that slows down your
website’s performance is database indexes. If
database indexes aren’t used properly or are
not used properly, then the website
performance may slow down. Database indexes
serve the same purpose as indexes in a book;
every index element has the required object’s
name and an identifier showing its location.
The primary purpose of creating database
indexes is to search for matching data instead
of going through all the searches in the
database.

19. Database Denormalization
It is a speculative correction of any
normalized database, so it doesn’t give up
standard forms. Denormalization reduces
the time required to select queries and adds
redundant data into existing tables to make
it more accessible.

20. In computing, caching is the process of
storing data and reloading it so that future
requests for that data can be served faster,
and the web page isn’t rendered repeatedly
for each user.
Caching allows users to work with the bulk
of data quickly while using minimal server
resources to be implemented on the client
and server-side.
3. Server and browser
caching

21. Fragment Caching
Fragment caching typically refers to
boundless caching. Your website’s web
pages are cached using fragment caching for
dynamic web applications that may quickly
become irrelevant. Complex web apps
contain many blocks and components, so it
needs to be re-rendered when any
modifications are done to the web pages.
Page Caching and Action Caching
Page caching is the most effective and
widely used caching for performance
optimization, which is wholly implemented
on the webserver. After executing on the
web server, it returns cached static content
to your application. But in some cases, page
caching is not suitable for applications
having frequent results that would produce
content a user has seen before.

22. Caching enhances your website
performance by diminishing the load time
and server load time because every cached
web page can be conveyed to users’
multiple times.
4. Web hosting service
Web hosting services are for backups and
server management. It helps to improve
your website performance depending on
the web hosting service and web hosts with
various capabilities and scalability options.
Compared to all web hosting, shared web
hosting is the most popular, widely used,
and popular web hosting.
Here we’re going to cover VPS, cloud
hosting, and dedicated hosting that plays a
significant role in performance
optimization, and it has enough capabilities
to improve your website performance.

23. Virtual Private Servers
A low-cost shared web hosting package and
costly dedicated hosting connect the VPS
that extends a personal virtual server for a
specific client and configures shared
hosting considering your configurations
don’t affect other clients.
The prices of VPS are affordable, but it may
go up if your website requires some
additional services. It is an optimal solution
for your website, having average traffic that
expects traffic spikes during specific
periods.

24. Cloud Hosting
Cloud hosting is suitable for small and
medium businesses implementing
applications with uncertain traffic for
eCommerce websites. Computing resources
becomes easy if you’re using cloud services
and pay only for what you use. Therefore,
with cloud hosting, you’re not required to pay
for resources that your website doesn’t use.
Dedicated Hosting
Dedicated hosting offers you a dedicated
server that pertains only to you, which is an
unreasonable solution. First, you’re obligated
to pay the server rent, which is $150 per
month. Secondly, you should have a system
administrator that can manage your server.
This way, with dedicated hosting, you get all
the power and resources that you need from
the operating system to the type of memory
where security and speed are critical.

25. 5. Content Delivery
Network (CDN)
Content delivery network, commonly
referred to as CDN, is a distributed proxy
server called “edge servers.” its
functionality helps you cache static content
such as CSS files, JavaScript, and images,
which is also dynamic cache content.
It helps to improve your website
performance, enhancing page load speed
and performance on its server’s location to
decrease your performance.

26. Reduced Costs
CDN allows users to retrieve requested
content faster. Imagine that any user from
the USA is trying to retrieve content from a
server-based India. If your website is
working great and gaining popularity, it is
proof that more people will access it. Do you
think these issues might have caused your
website performance in the past? If yes,
then not to worry, you will get solutions for
these back-end issues once you complete
this blog.

27. What are the
solutions for
front-end
issues?

28. When you request to load a web page, the
browser requests for its images,
overlooking other things like whether
they’re in the viewport or out of sight. With
lazy loading, all the visible images and
asynchronous load the rest on-demand
when the user scrolls. It helps you to
improve your website performance,
reducing the loading request.
1. Lazy Loading

29. Lazy loading was implemented with the
Intersection Observer API in 2019. The
exceptionally well-written tutorial was
implemented by Google showing the
importance of lazy loading, which you
should check out if it’s something you’re
looking for.

30. It is another significant way to reduce your
website’s page size for the better use of
viewport space. To show the appropriate
image size depending on the viewport size,
implement the srcset and sizes attributes
like:
< picture >
< source media="(max-width: 799px)"
srcset="dog-480w.jpg" > < source
media="(min-width: 800px)"
srcset="dog-800w.jpg" >
< img src="dog-800w.jpg" alt="A
picture of a dog" > < /picture >
2. Responsive Images

31. In modern front-end development,
Bootstrap is a suite of highly reusable
classes for creating quicker and more
responsive UI creation.
Here is the example showing a typical grid
system implemented using Bootstrap:
All the classes shown in the following
example create columns with full-width and
generate a classic 3-column layout. It is
generated in SASS file-based on the
breakpoint variables provided to Bootstrap.

3. Remove Unused CSS

32. With the help of compression devices like
gzip and Google’s Brotli, it is so convenient
to decrease the file sizes requests:
When you compare the CSS and JS files,
you’ll notice that the PNG’s compression
ratio is pretty dull. Gzip and Brotli are
perfectly suited for text-based files where
the repetition rate is pretty higher for the
compression to be more successful.

35. Not only this, but a full stack web developer
can also help you with other tools and
technologies to improve your website
performance and scale up your business.
If you have cross-platform applications
built-in Flutter, React Native, Ios, Android,
Ionic, they are well-versed enough to help
you with 360-degree solutions.

36. Currently, a typical user expects web pages
to load less than after 3 seconds. If you don’t
meet this expectation barrier, you lose a lot
of website traffic and, as a result, your
revenue.
So, website performance is the most
important concern for any digital product
owner who has to look into it frequently,
regardless of its size. Nobody likes a slow
website. So, I hope your purpose of landing
on this blogpost is served, and you got a
better understanding of why you should
hire full stack developer or a team to
improve your website performance. Full-
stack developers are the ones who are well-
versed and skilled enough in offering top-
class solutions for both front-end as well as
back-end issues.
