First Byte & gzip issues

RE: First Byte & gzip issues
The 2.4 second first byte time is killer and not something we can debug from the outside. Since it's a VPS, can you install NewRelic (or something similar)? They have a free offering and a 2-week trial of the full product which should be able to tell you exactly what is slow on the back-end. Otherwise it's going to be a matter of instrumenting the code to isolate the slow bits.

Being a wordpress site, take a look at your plugins and make sure you really need all of them. They tend to like to make a lot of database queries and 9 times out of 10 that's what makes things slow.

It's worth installing the W3 Total Cache plugin and enabling the database and object caches (as well as the page cache if the main page is mostly static), preferably with apc if you can install that as well. That will eliminate the overhead with repeated database calls and can usually eliminate most of the slowness.
