WP SuperCache Rocks

April 16th, 2010

I installed about a year ago and was curious to see how welll it really works…

Baseline – hammer with 1000 hits, concurrency = 10. Uptime (load1) remained around 0.6 over the duration of the test:

Disabled wp-supercache, emptied cache and retested – used only 200 to start with – uptime (load1) was around 9.0!

enabled cache, test one more time. Inititally php processes were high – then after about 10 seconds tapered off and http was the dominant one, though at 0.6 again for load1
