Hello Ben, >If you want to put this to the test, consider disabling prefetch and >trying again. See >http://www.solarisinternals.com/wiki/index.php/ZFS_Evil_Tuning_Guide
i should have read and follow advice better - this was the essential hint. thanks very much. after issuing echo zfs_prefetch_disable/W0t1 | mdb -kw the problem immediately went away ! so, why does solaris have such stupid default set ? is my workload that special? i cannot believe that i`m the only one with this problem or the only one using zfs for backing up large files.... -- This message posted from opensolaris.org _______________________________________________ perf-discuss mailing list perf-discuss@opensolaris.org
