Confusion on TTFB - jasper527 - 06-03-2013 11:39 AM

Hi,
I have two sites that are very similar to each other. One is a staging site and the other is my live site. The live sites loads faster, but the TTFB is slower on the live site than the staging site (by around .5 secs). I'd love to be able to recover that extra .5 seconds on my live site. Both are hosted on the same server.

I can't figure out what the issue is. Here is a comparison:

Thanks,

Alan,
It looks like your html for the live site is about 6x your staging site (~600k vs ~100k).

Depending on where your server lives, we're dealing with physics - bytes of data can only travel so fast! Do you have compression enabled on your staging server but not the live one? Looking at bytes of JS transferred, that may be what you're missing.

What is really positive is your start render time is better for live - so there is a better chance the customer sees something sooner!

Hope that helps!
Ben
