I've been trying to narrow down performance problems I've had with my freenas server for some time now. Transfers are painfully slow when using Lightroom to import RAW photos from an CF card a folder on my local machine to my network share (via Gigabit wired connection). Most of the performance problems seem to be with writes. I finally took the time to go through the performance tuning thread and benchmark my system.
