I have been addicted to the page speed now for some time since i see google is as well. I did a complete re-design of my site and it appears fast but webpagetest shows an F for first byte and it shows about 2 seconds for it. Now loading the page on a non cached browser seems much fater than 2 seconds though.

Now the things I have done

  • Dedicated peer1 server (centOS x64) server loads around .40 .30 .40
  • Running FastCGI
  • Installed xcache (confirmed working)
  • compressed all images

The site runs on vbulletin mainly, with custome scripts on top of VBCMPS content management (only to integrate with VB)

I ran a speed test in microtime on the start to finish for the index file that produces the pages and it reports an average speed of .02 seconds for all processing.

I just do not see why the rate on first byte seems off?

My last step I was planning on is rem oving .htaccess files and inserting into the http config and turning off allow ovveride.

Any input would be great!

Thanks Chris

  • Have to guess but it sounds like your server-side is doing some processing before sending the first byte. Doing a database query for a session or something? Profile your PHP to see if there's a big delay in it. – Zan Lynx Apr 05 '12 at 21:22
  • Or, it might be a network path issue between you and webpagetest. Maybe some system is blocking the ICMP needed for MTU Path Discovery, or ECN is being blocked and disabled, or there's a flapping route cache somewhere ... – Zan Lynx Apr 05 '12 at 21:24
  • as far as php i ran the microtime start as the first line of the index.php and did an output right before the vbulletin create page and that was .02 seconds for all my code. Now VB may be taking some hit with the output but I also ran all the base building blocks of vb with that .02 time.. – Radium Chris Apr 05 '12 at 21:34
  • Also, by adding xcache, and enabling fCGI I really saw no increase in page speed, although I was hoping to see a dramatic difference I really got nothing measurable over suPhp – Radium Chris Apr 05 '12 at 21:49
