Yes, but.....

If you reduce the compression level then the disk will be hit harder, 
which means that your io load will go up.

About compression:

There is no need to use compression if the client's connection to server 
is 1Gb/s or faster and not much point at 100Mb/s. (Compression 
frequently slows things down at higher speeds as the CPU becomes a 
bottleneck. Using it is a tradeoff.)

Compression is one of those things best only used for backups across a 
WAN. If you myst use it, then _benchmark_ things with and without. Most 
of the time where you think it will benefit communications on the wire 
you will find it actually penalises throughput.
