Has anyone else noticed a significant zfs performance deterioration when running recent opensolaris bits?
My 32-bit / 768 MB Toshiba Tecra S1 notebook was able to do a full opensolaris release build in ~ 4 hours 45 minutes (gcc shadow compilation disabled; using an lzjb compressed zpool / zfs on a single notebook hdd p-ata drive). After upgrading to 2007-05-25 opensolaris release bits (compiled from source), the same release build now needs ~ 6 hours; that's ~ 25% slower. I think a change that might be responsible for this is the fix for 6542676 "ARC needs to track meta-data memory overhead" (that is, less caching with the fix for 6542676). Has anyone noticed similar zfs performace deterioration?
