Analyze Your Website’s TTFB (Time to First Byte)

I’ve been using this service for quite sometime to analyze TTFB. I also use curl via local server command line and/or my laptop as well as other methods. This website I’m sharing is useful when combined with other data/methods of troubleshooting TTFB and overall site response. It is…

Note: High TTFB on a site with little traffic is inexcusable, this is more useful for servers under heavy traffic loads.

Results will look something like:

Try to keep TTFB under a second, repeat tests should be lower. Need professional help? Hire me

The ByteCheck test website is located in Chicago (last checked) so factor geographic distance into results. Compare with other servers and use CURL to test from your Linux or Mac using terminal apps. Example from my Arch laptop:

[root@archlinux]# curl -o /dev/null -w "Connect: %{time_connect} TTFB: %{time_starttransfer} Total time: %{time_total} \n"
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100 23283    0 23283    0     0  70576      0 --:--:-- --:--:-- --:--:-- 70768
Connect: 0.144 TTFB: 0.226 Total time: 0.330 

TTFB can often reveal if you are having issues with server overload or inadequate network.  Hope this helps.
