When it comes to the overall speed of your site, we often focus on front-end performance and optimizations to improve page load speed .
However, sometimes it’s nice to see it from the server side, where your website starts loading.
Today we’re going to dive into how TTFB (time to first byte) affects us and discuss some easy ways on how to reduce it. TTFB is a commonly overlooked performance factor, but you should consider it when testing your site speed.

- 4 Ways to Reduce TTFB on Your How to Reduce Site
What is TTFB?
TTFB stands for Time To First Byte. To put it iran email list simply, this is a measure of how long the browser has to wait before receiving its first byte of data from the server. The longer it takes to get that data, the longer it takes to display the page. A common misconception is that this is calculated after DNS lookup times, however, the original TTFB calculation on networks always includes network latency. This involves a 3-step process and delays and latency can occur anywhere in between, adding to your total TTFB.
1. Request to the Server
When someone visits your website, the first thing that happens is that an HTTP request is sent from the client (browser) to the server. There expanding the brand’s global appeal How to Reduce are a variety of factors at this stage that can introduce delays. Slow DNS lookup times could contribute to increased time for the request. If the server is geographically far away, this can introduce latency into the distance the data has to travel. Also, if you have complex firewall rules, this could increase routing time. And don’t forget the speed of the client’s internet.
2. Server Processing
Once the request is sent, the server now has to process it and generate a response. This could introduce a number of delays such as anhui mobile phone number listslow database queries , too many third-party scripts, not caching your first response, poorly optimized code for the topic, and inefficient server resources such as disk I/O or memory.
