Something weird just happened!
We've just done a major overhaul of our corporate website and I was thinking of finally going ahead and apply Google, Yahoo, Pingdom and GTMetrix recommended changes to improve speed.
Before the overhaul, our page loading times clocked in at an average of 11 seconds. (I know, I know...but it was a really old design and the previous developer had done wonky things to our site anyway.) After we were through with updating it+using a clean Wordpress install? 2.85 seconds.
Feeling somewhat greedy, I decided to see if I could get our PageSpeed and YSlow grades up (currently C, D) and reduce page load times EVEN MORE. So I went ahead and made two quick changes that had been recommended to us over and over again, following instructions as provided by the respective authorities: enabled compression, leveraged browser caching.
...Page load times skyrocketed to 25.56 seconds! That's right: nearly half a minute.
GTMetrix, PageSpeed, YSlow quickly gave our website revised grades of B and C before dying (in case of the PageSpeed analysis) or informing me my website is slower than 94% sites on the Internet (duh!)
So I rushed back, reverted the changes I had made, and viola. We're back to serving up pages in under 3 seconds. Even though Google et al are now angry at me and have bumped our site back a grade.
My question: What.the.frack?
