If you have Wordpress, Use WP Super Cache
In: Blogging| GrabPERF| Internet| Web Performance
11 Sep 2009I just did a quick experiment to validate my hunch, and it’s true – WP Super Cache can cut your HTML load time in half in your WP deployment. Just check out the GrabPERF Measurement that backs this up.

Turns out the solution is built right into PERL: The Socket module.
My thought is that I will [...]

The goal of the index is to provide performance metrics for a group of search providers around the world. The results are based on a direct HTTP GET request being made for the search results page by the GrabPERF Agent.
Currently only live [...]

GrabPERF Instability this week
In: GrabPERF
13 Mar 2009Over the last seven days, GrabPERF has been running in a very unstable state. This appears to be directly related to the use of InnoDB as the DB engine on a few of the larger tables in the database. [InnoDB changeover discussed here]
Today, the system was offline for several hours before I noticed that the [...]
