gzip compression throttles system?
I just had a quick play with gzip compression on a filesystem and the
result was the machine grinding to a halt while copying some large
(.wav) files to it from another filesystem in the same pool.
The system became very unresponsive, taking several seconds to echo
keystrokes. The box is a maxed out AMD QuadFX, so it should have plenty
of grunt for this.
Comments?
