If I can help narrow the variables, I compiled both 137 and 144 (137 is minimum req. to build 144) using the same recommended compiler and lint, nightly options etc. 137 works fine but 144 suffer the slowness reported. System wise, I'm using only the 32bit non-debug version in an "old" single-core/thread pentium-m laptop.
What I notice is that the zpool_$pool daemon had a lot more threads (total 136, iirc), so something changed there but not necessarily related to the problem. It also seems to be issuing a lot more writing to rpool, though I can't tell what. In my case it causes a lot of read contention since my rpool is a USB flash device with no cache. iostat says something like up to 10w/20r per second. Up to 137 the performance has been enough, so far, for my purposes on this laptop. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
