Pingdom "wait" times?

[ohhai]

Hey guys,

Set up Cloudlinux and Litespeed. Ive also setup eAccelerator and memcache, along with LS cache. Ive tweaked as many settings as I can and have a decently filled wordpress site down to an average ~1.4second load time on Pingdom from a local server.

My question is, the 'wait' times all have a minimum 80ms, where as I tested another server running nginx and wait times are practically nil (single digits).

My understanding is that Pingdom's wait time is the period at which the server is processing the request, before it outputs any data to the browser. The site performance is good, perhaps Im paranoid, but why is this so much higher?

Thanks for helping in the ever continuing quest for speed.

you can use http://www.webpagetest.org/ to test website's performance.
it should give much more detail than pingdom.
and everyone can access the test result once you provide the URL, so we can discuss about it easily.
