I seen that my vbulletin site time to first byte is 370 miliseconds (too big ) even when im loading plain php file with echo "someshorttext";

any idea please how to improve? I got mod_deflate, apache, php... - root access to server

EDIT

The target first byte time is 282 ms so on the test you ran you're not far off. This will vary depending on several factors including load from other sites on this shared server. As you can see on this test just ran, you're grading well on first byte time for that test occasion..

WebPageTestResult

On these tests today, it appears there is a redirect you need to look into getting rid of. Call #1 is the forum, call #2 is the forum with a trailing slash. It is taking time to resolve this unneeded redirect and that is affecting your first byte time and the start of rendering.

On this page are all of the images you are loading. Use the third image you see here instead of the one you have now, to save 66kb on page load.

You are getting a failing grade for "Leverage browser Cache of static assets" and that is a easy fix, just install the following code into your .htaccess file:
