There was not much progress with performance test as mentioned here.

I first did test with LDAP vs. memcached, then found there was not much difference between those two, which is suspicious, so I started running test to compare pure database and memcached solution, which ideally should show lot of difference, but I failed.

I still haven’t figured out what was the real cause, it seems VM is not that good to do this kind of test – thinking of limited resource (CPU, mem, network, disk, etc), all VMs will compete each other. Again, this is my guess and I will try to see what would be the best solution to get performance done in VM environment.

Even if I failed, it shows that VM will not be good for performance testing, nice try ๐Ÿ™‚ .
