I'm running an AMD nforce4 system with two 80GB 10k SATA drives for the OS on the si3114 controller in a RAID 1 config, and two 400GB 7200 SATA drives in RAID 1 on the nf4 controller. It's a nice system, and quick.
However, I'm wondering if I'd get better performance compressing the system drive. Space isn't an issue, but it seems to me that with a fast CPU, the overhead of decompression may more than offset the fact that less actual data is transferred from disk to memory, meaning fewer sectors read, which should be quicker.
A quick google hasn't turned up anything substantive. Has anyone seen benchmarks on how compression affects real world performance, and how that relationship changes with disk and CPU speed? Or do I have to do it myself?
Cheers
