Deleting files is extremely slow on my box, it's be bugging me for a while but I've only just had a chance to look into it. It is slow deleting files over the network (smaba, windows file manager gets stuck "calculating") which at first I blamed on smaba (and windows) after the last batch of it playing up I decided to try locally (root, using rm -rf) and it was just as slow. I'm talking 5ish minutes for a 2gb file.
As far as I can see I'm not even touching the ram (58gb free during delete both network and locally).
All other operations are working as expected (read, copy etc...)
Any advice on where to look or where the issue may lie?
Setup details:
11.0-U4 (has happened since 9 when I installed)
Intel Xeon E5-1620V4 2011-V3
64gb ecc ddr
12 x 8tb WD Reds (6x mirrors)
2 x 400gb Intel 750 pice ssd (mirrored, logs)
No compression
No dedupe
