Server Response Time – How to reduce server response time?

Server Response time

Server Response time

Server response time is how long necessary HTML takes to begin rendering the page from your server by subtracting the latency between you and the server. It is one of those factors which affect the speed of your webpage.

Therefore, it is important to keep Server Response Time (SRT) as low as possible because it will help you to improve website’s overall Search Engine Optimization (SEO).

A website which has good SEO ranks itself higher in search engine results. The higher your website appears in search results, the more traffic is likely to occur. There are many approaches which can be incorporated to improve overall SEO. You can read about the following two factors:





  1. Sitemaps – What is a sitemap and how often you should update it?
  2. How WordPress plugins slow down your website?

How to reduce Server Response Time (SRT)

According to Google Page Speed test, the ideal server response time should be under 200ms. You can check your website’s server response time on Google’s Page Speed Insight.

Ideally, webmasters consider server response time as the last factor which needs any kind of improvement because it accounts for only 10% out of the other 90% factors.

Now, let’s catch up with the majority of the factors which affect server response time and how can they be improved:

1. HOSTING SERVICE

Hosting Service

At first, many of us don’t think twice before buying a hosting service but it becomes a major factor in terms of server response time. There are many big fishes in the market which have a good brand name and offer to host at minimal prices.

You should not fall for the lucrative traps these companies offer because when you finalize a hosting service it becomes important for you to determine which hosting service provides the best web resources.

Select a hosting service which provides adequate CPU usage, Memory usage, I/O usage and File usage. Speaking about my personal experience, I faced issues in Memory Usage and I/O usage. There are many background processes which occupy abundance of memory and results in overutilization of RAM.

Over-utilization results in downtime and therefore I recommend you to select the best hosting providers. I have personally used Godaddy’s hosting service for more than 2 years and I do not recommend you to go for it. It is cheap but comes cost of downtime and limited web resources.

2. DATABASE

Database

If your website runs primarily on the database and returns results through database queries, then, you should definitely read further…

The database which executes slow and complex database queries increases server response time. It is the primary bottleneck when it comes to server response time. So, a reduced server response time highly depends upon database optimization and how fast are your queries.

How can I optimize database and queries?

If you have landed on this page I assume that you have a bit of technical knowledge. I will not go too deep into technical rather I am going to tell you the basics to help you in long run optimization of the database.

  • Ask yourself a question; is there any part of the database which can be brought from backend to front end?
    As it provides additional security I understand your motive of keeping the database in the backend. Think consciously and find out which databases can be brought to the front end. Once, you have decided, figure out the ways to cache it. You can use third-party plugins to that work for you. If there are no such databases which can be brought to the front end then you can skip to next part of this article.
  • Use Appropriate Indexes
    If the indexes aren’t sorted properly or have a gap between each other, run maintenance because Indexes plays an imperative role in executing database related queries.Mostly, they are used as primary key in discrete tables, therefore, if indexes are properly sorted then database queries like addition, deletion and updating become easy.
  • Rewrite Queries
    It is necessary to rewrite queries if they are not returning what is required. If you are running 2 or more queries which return the same result then cut the number. Use queries which are thoroughly written for performance only.
  • Change Schema
    It is always better to change the structure of the table and lineup the data accordingly.

3. COMPRESS IMAGES

Adding additional images to your web pages might look very fancy but they put up oodles of burden on the server. Therefore, each time you request a webpage all the images on that page is downloaded. If the image sizes are big, the more time it takes to get downloaded.

4. REDUCE NUMBER OF REQUESTS BETWEEN CLIENT AND SERVER

The number of requests means how many times communication takes place between server and client to fetch and render a webpage.

A web page typically contains HTML files, stylesheets, and scripts. If too many requests are made between server and client, the server response time increases exponentially.

Hence, you can use online tools to minify HTML, stylesheets, and scripts as it saves a lot of space and reduce server response time. If it is not possible then try to load scripts asynchronously because seventy percent (70%) of the requests are made by scripts.

5. COMBINE EXTERNAL CSS, JAVASCRIPT, and LIBRARIES

This is one of the best ways to reduce server response time. If your web pages contain too many external Javascripts, CSS and libraries then combine them under the single-hood (obviously under the respective categories).

By doing this, you can almost minimize the number of requests between server and client and thus improve server response time.
