The system seems a bit slow in response time.

I have very strong opinions regarding tuning. I believe that all tuning
has two prerequisites:

1) A goal expressed as numerical quantities vs a specific time frame.
For example: Between 10 and 11 AM 90% of interactive jobs will have
subsecond response time.

2) A measurement which can be used to judge where the system is.

After the prerequisites are met, keep records of
a) what got changed
b) the new measurement

This way you will be able to undo any adverse adjustments, as well as
start to pick out patterns of how your system handles various workloads.
