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...

If the issue is unrelated to TRIM, please post details to a separate topic. Thanks.
