Running a 5.2 supped as of 4/9. I have the UFS_DIRHASH stuff compiled into my kernel. Is there some other frob to actually "turn" it on? I run softupdates, and moving files from my local box over gig ethernet to a directory with 5000 files in it is moving about 1 file every 6-7 seconds. If I move the same files to an empty directory, they move so fast I can' even read the names, which is more "normal". Even directories with 2500 or so files seem really, really, really, really slow. at least for adding/removing. My FS is UFS2, on a 3ware RAID controller. I would love any ideas. smbd is burning up 60-70% of the CPU, I've tried kernels with and without all the witness/diagnostic and all that stuff.
