you have a number of options:
All good ideas and I'll be sure to implement them later.

I am curious why you need to query the count of records in the log
table to six digits of precision.
I'm not with you you here.
I'm drawing statistic for the my users on a per user basis in real-time, so there are a couple of where clauses attached.

Hi Merlin,

This was just an example. All queries have slowed down. Could it be that I've reached some cut-off and now my disk is thrashing?

Currently the load looks like this:
Cpu0  : 96.8% us,  1.9% sy,  0.0% ni,  0.3% id,  0.0% wa,  0.0% hi,  1.0% si
Cpu1  : 97.8% us,  1.6% sy,  0.0% ni,  0.3% id,  0.0% wa,  0.0% hi,  0.3% si
Cpu2  : 96.8% us,  2.6% sy,  0.0% ni,  0.3% id,  0.0% wa,  0.0% hi,  0.3% si
Cpu3  : 96.2% us,  3.2% sy,  0.0% ni,  0.3% id,  0.0% wa,  0.0% hi,  0.3% si
