Web Performance, Branding, and Social Media

5 Mar 2009Today we undertook two maintenance and upgrade tasks at GrabPERF that have been neglected for too long.

Ok, I got manic. Goes with my life.
As a part of that mania, I had a breakthrough on how to present GrabPERF data that I’ve actually been collecting for nearly a year: text match failures.
GrabPERF has the ability to match text on page results using a standard PERL regex. By putting [...]
