Hi David,

Using ab with DISABLE_CACHE set to false:

Requests per second:    3.47 [#/sec] (mean)
Time per request:       288.096 [ms] (mean)

With DISABLE_CACHE set to true:

Requests per second:    3.67 [#/sec] (mean)
Time per request:       272.454 [ms] (mean)

Its about the same. With the wp-cache plugin, I used to get up to 100  
requests/sec out of WP 1.5, and about 3.5/sec without the wp-cache  
plugin - which is very similar to the numbers I'm getting out of WP  
2.0.1, which suggests to me that even though objects are getting  
written to disk, it's always going to the DB for every request.

It could be a combination of my plugins, but disabling everything and  
dropping back to standard 2.0.1 doesn't seem to have an effect.

I'll have a dig and see if I can find something.

Can someone else do some ab's against 2.0.1 and compare it with 1.5  
running wp-cache? I'd like to know if I'm the only one seeing a  
difference here.
