My php.ini shows memcache (not the pecl memcached) running and configured. A simple (non Yii) PHP script fetches values out of memcache correctly. I’ve also run some of the scripts from the memcache site and there were no failures. phpinfo() shows: memcache version 3.0.1 - so I think memcache is running fine.
However, when I have caching enabled, I am not getting the request per second I would expect. I’m using Yii 1.1.6
Testing one page with apache benchmark "ab":
Static html version of page (non Yii): 1200 requests / second
Yii Page Caching using file caching: 90 requests / second
Yii Page Caching using memcache: 60 requests/second
Yii No caching for the same page: 17 requests / second
Admittedly I am doing this test on a lower end notebook, so the numbers are bit small, but regardless the memcache number should be higher than the file caching option. And I assume memcache is "working" since 60 is higher than 17, but I would think that number should be higher than 90 at the least.
When running the "ab" test, with either caching option no database queries are being made.
Is there a way to log or test the Yii caching to see exactly what it is doing? Or any other troubleshooting steps to see why memcache is slower than file caching?
