The process of optimizing the site is multilevel, but one of the key aspects remains the server response time. What it is, what it depends on, and how to reduce it – we will tell further in the article about this.
Server response time (TTFB) is the number of milliseconds it takes the server to process the client's HTTP request and generate a response. Accordingly, the less time it takes the server to respond, the faster the page will load on the visitor's computer.
Time To First Byte is one of the key metrics that determines how long it takes the server to load HTML code. The TTFB is affected by several factors:
All of these factors are analyzable and can be improved with various tools to reduce the time to first byte as much as possible.
The optimal server response time should not exceed 200 ms or 0.2 sec. Ideally, you should aim for 5-20 ms, but this is not always possible, especially in the case of large information sites, portals, and online stores with lots of different scripts, images, graphs, and other voluminous elements.
Consider three key tools for such a metric.
A simple and extremely effective tool that works in the cloud. To check the server response time, the webmaster just needs to go to their official website and enter a valid URL into a special field, and then click "Analyze". The analysis will take a few seconds, after which you will see the scores for the key indicators:
For convenience and information service also offers a visual scale, which will allow you to understand what indicators your page is normal and which require further optimization.
Official service developed by Google corporation has a huge number of different tools that collect comprehensive information about the site. All this is competently structured and is brought to the administrator's attention in the form of tables, summaries, and statistics.
Concerning the speed of loading the site – Google Analytics not only analyzes the loading time of pages but also provides immediate and specific recommendations on internal optimization. The column "PageSpeed Suggestions" contains links to various tips for each individual page.
It works on a similar principle, but the analysis is deeper and takes more time – about 20-30 seconds. Outputs metrics on 7 key indicators:
Each indicator is colored in a certain color, depending on the deviation from the norm. At the output, you get a complete picture of the speed of loading pages and the state of their optimization.
There are 5 categories of factors that affect the server response rate:
As we noted above, the type of hosting seriously affects the response time of the server, as a productive server increases the speed of processing requests. There are three options:
When choosing a server, it is important to understand what amount of resources will be optimal to ensure the operation of your projects. We are talking about:
It is clear that you can always rent a server with a large reserve in terms of capacity and not think about this kind of nuances. But if saving money is critical, you need to carefully approach the choice of configuration – any experienced webmaster can help with this, analyzing the data of your site, traffic level, and other parameters. Based on this analysis, the specialist will be able to specifically say which configuration will be optimal for you. You can also consult the HostZealot specialists in this matter.
Let's walk through the key ones:
So, by optimizing various aspects of the server you should strive to reduce the server response time to 0.2 seconds. This is the optimal indicator, which should be guided by all owners of popular sites with a high level of traffic. Pay attention to the recommendations provided by the service Google Analytics and apply them in practice - this will help to achieve the desired results.
