I definitely have to agree with this statement in general. In my 12-core 24GB RAM Mac Pro I have 4x2TB drives (WD Greens, not the fastest drives in the world, but certainly not molasses-slow); I had originally configured them as RAIDZ2, but have now reconfigured them as 2 2-drive mirrors in a single pool... and my home directory lives on that pool, and everything is
abysmally slow. I'm talking hanging for seconds (and tens of seconds!) at a time when doing even simple Finder operations, trying to play tracks in iTunes, etc.
I have done the right ashift thing, have atime turned off, have the pool only about half full, and have experimented with various settings for compression (currently "off") and the like - and I've been using this software since the early Z-410 days. I'd love to know what it is I'm doing wrong that makes my system so unlivable when everybody else seems to have no complaints...
