WP Super Cache Benchmark
If you’ve thought about whether upgrading from WP Cache 2.0 to WP Super Cache is a good idea, hopefully this benchmark will convince you. I followed my instructions on benchmarking Wordpress with Apache Bench on four configurations of this blog’s main page to measure performance:
- Without any caching plugins
- With WP Cache 2.0
- With WP Super Cache (no compression)
- With WP Super Cache (compression enabled)
The results show that WP Super Cache is a clear winner, performing 225% better than the older WP Cache. Here is the raw data I gathered during the test:
No caching:
Requests per second: 22.81 [#/sec] (mean)
Time per request: 4383.559 [ms] (mean)
Time per request: 43.836 [ms] (mean, across all concurrent requests)
Transfer rate: 613.75 [Kbytes/sec] receivedWP cache:
Requests per second: 872.30 [#/sec] (mean)
Time per request: 114.640 [ms] (mean)
