.Nuno. Posted May 13, 2013 Share Posted May 13, 2013 Hello, For those who can connect using ssh, what is you time to first byte? Please show the average for 3 runs. curl -o /dev/null -w "Connect: %{time_connect} TTFB: %{time_starttransfer} Total time: %{time_total} n" http://inserturl.here Mine is: 0,362 user@host:~$ curl -o /dev/null -w "Connect: %{time_connect} TTFB: %{time_starttransfer} Total time: %{time_total} n" http://www.myboardurl.tld % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 195k 0 195k 0 0 450k 0 --:--:-- --:--:-- --:--:-- 452k Connect: 0.006 TTFB: 0.397 Total time: 0.434 user@host:~$ curl -o /dev/null -w "Connect: %{time_connect} TTFB: %{time_starttransfer} Total time: %{time_total} n" http://www.myboardurl.tld % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 195k 0 195k 0 0 560k 0 --:--:-- --:--:-- --:--:-- 565k Connect: 0.005 TTFB: 0.338 Total time: 0.348 user@host:~$ curl -o /dev/null -w "Connect: %{time_connect} TTFB: %{time_starttransfer} Total time: %{time_total} n" http://www.myboardurl.tld % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 195k 0 195k 0 0 535k 0 --:--:-- --:--:-- --:--:-- 537k Connect: 0.004 TTFB: 0.353 Total time: 0.365 Is this good or bad?

Dmacleo Posted May 13, 2013 Share Posted May 13, 2013 wouldn't you have to run that from a 'nix client to the server? Link to comment Share on other sites More sharing options...

.Nuno. Posted May 14, 2013 Author Share Posted May 14, 2013 For those who would like to show us the results, can use a service like Gomez and choose the nearest server.

p4guru Posted May 14, 2013 Share Posted May 14, 2013 why not use webpagetest.org more geographic locations to test from as well :) Link to comment Share on other sites More sharing options...
handsoffsam Posted May 14, 2013 Share Posted May 14, 2013 Yup, yup, webpagetest.org is the tool or the job, IMHO. My TTFB is terrible, about a second: http://www.webpagetest.org/result/130514_P3_W88/ I believe this is mostly due to nginx/php-fpm interaction. My understanding is that the way the FCGI protocol buffers output, it is basically not able to start sending the first byte until the whole page (or at least, a large part of it) has been completed. robert Link to comment Share on other sites More sharing options...
jdrago Posted May 26, 2013 Share Posted May 26, 2013 On Hostgator VPS my TTFB rated an F - Is that a typical issue with VPS? Or something I can correct? Link to comment Share on other sites More sharing options...

Royzee Posted June 6, 2013 Share Posted June 6, 2013 It seems to me that time to first byte would be useless unless you have a PHP bottleneck problem. Link to comment Share on other sites More sharing options...
mat206 Posted June 6, 2013 Share Posted June 6, 2013 It seems to me that time to first byte would be useless unless you have a PHP bottleneck problem. PHP bottlenecks are specifically what this test identifies.. the time it takes to actually generate the response. For my site we generate responses really fast, but probably are a bit too script heavy to give quick load times. The default IPC weighs in at roughly 250KB where we have that jacked up to around 600KB. Link to comment Share on other sites More sharing options...
p4guru Posted June 6, 2013 Share Posted June 6, 2013 TTFB when slow is usually more a problem with MySQL database backend than PHP as PHP has to wait for response from MySQL server ;) Link to comment Share on other sites More sharing options...
