Btw: Should I be using this version (2.9) regarding speed - if I'm disabling
this caching system?
My site handles hundreds of requests a second, and I'm currently using a
modified version of 2.0.x which is mostly dealing with it - Should I attempt to
implement this version, or wait a bit.

The bad thing is: I haven't got any IIS to test. :(This issue can stay open for
a long time unless someone decides to send patches)
But I would recommend using 2.9.2 (in trunk).
Instead of disabling the caching system, try to avoid using the "sort" class.
Then field caching will not be used.
(This means you have to sort your results by yourself).
