I’ve installed new plugin to my blog. It’s called WP Super Cache. And I want to show you some benchmarks.
I download siege to make benchmarks:
apt-get install siege
Then prepared list of urls, actually I took it from my sitemap.xml and normalized it in next format:
root@laptop:~# head url.txt http://andriigrytsenko.net http://andriigrytsenko.net/2011/07/apache-vs-nginx-vs-lighttpd-and-static-content http://andriigrytsenko.net/2011/07/ldap-mss-replication http://andriigrytsenko.net/2011/07/pacemaker-and-apache
Then run siege with/without caching plugin with next arguments:
siege -t1M -i -A 'Chrome/12.0.742.112 Safari/534.30' -f url.txt
where
-t1M – means run siege during one minute
-i – download links randomly from the list
-A – user-agent description
-f – path to file contains urls.
And get next results:
| Description | With caching | Without caching |
|---|---|---|
| Transactions(hits) | 1609 | 252 |
| Availability(%) | 100.00 | 100.00 |
| Elapsed time(s) | 59.82 | 59.72 |
| Data transferred(MB) | 16.75 | 10.30 |
| Response time(s) | 0.05 | 3.01 |
| Transaction rate(trans/sec) | 26.90 | 4.22 |
| Throughput(MB/sec) | 0.28 | 0.17 |
| Concurrency | 1.47 | 12.72 |
| Successful transactions | 1609 | 252 |
| Failed transactions | 0 | 0 |
| Longest transaction | 0.55 | 10.39 |
| Shortest transaction | 0.02 | 1.44 |
If you blog doesn’t have a lot of updates like my does, then apparently it is a good idea to install and active caching plugin.
