Compare server response time
You can view all monthly uptime and server response time results for a host on its review page (just click the links below).
Response time is a measure of how long it takes a browser to retrieve HTTP headers (meta data sent between the browser and server) and the first byte of data (referred to as “time to first byte” or TTFB), as well as load HTML (the source code for a web page).
We monitor response time and uptime for 18 of the world’s largest shared web hosts on a minute-by-minute basis. You can view the latest rankings below and rankings for March, April, May, June, July and August are also available.
While some web hosts frequently maintain response times in the low hundreds of milliseconds (ms), others maintain response times of 1 or 2 seconds. Google recommends aiming to keep response time under 200ms.
A response time of 1 or 2 seconds may not sound like a lot, however keep in mind response time isn’t page load time or page speed. In other words, the amount of time a user must wait for a page to load is often significantly longer than the response time of the server.

Response time vs. page speed vs. uptime
Response time is distinct from page speed. Page speed is a measure of how quickly a user-agent, like a browser, retrieves, loads or executes all requested assets, e.g., files, images, scripts, etc.
A single web page can comprise hundreds of dependent assets and take anywhere between 1 second and 20 seconds to load. Poor performing web pages can affect search rankings, reputation and sales.
- 53 percent of mobile users will leave a page that takes more than 3 seconds to load;
- According to Google, the average mobile page loads in 22 seconds; and
- A 1 second delay can affect conversion rate by as much as 7 percent;
In Google Chrome, you can view the HTTP requests and responses generated for a given page by right clicking on a web page, selecting “inspect element” and clicking on the network tab.
What affects response time?
Response time can be affected by any number of factors, including:
- Available server CPU resources;
- Server memory (RAM); and
- Poorly constructed database queries.
Many web hosts now utilize an operating system (OS) called CloudLinux, which partitions the resources of a server into what are called “lightweight virtual environments” (LVEs).
Rather than being afforded all the resources of a server, as was formerly the case, customers’ who purchase hosting packages from web hosts utilizing the CloudLinux OS will only be able to utilize the server resources assigned to their LVE.
As a single web server can host hundreds of websites, web hosts that utilize the CloudLinux OS can guard against any single user disproportionately leveraging server resources.
