If you are generating a lot of disk I/O to the swap file, you have other
problems.  By trying to optimize the swap file you're treating the symptom
instead of the illness.  It's sort of like giving a pain killer to treat an
infection.

Subject: Ahem, Server Configuration question for swap


Wise aged Exchange Pros:
Does putting the swap file on it's own spindle, gain much in performance?
Or is it better to just split the system mirror and put the swap on the
second half?

Proposed configuration is:
1. Mirror for system
1 Mirror for swap
1 Mirror for logs
1 Raid 0+1 for database

Total = 10 drives in this config
The Chassis holds 9 drives, so one option is to split the system mirror for
the swap partition or add an expansion chassis and move the database to make
room for the hot spare and keep the swap on its own spindles.

Performance isn't an issue, these boxes have MIPS to spare, but have any of
you noticed a gain in performance by separating the swap?   Any of you made
this decision, and why?
