Hi Mauro, Yes I understand why sysinfo is not the best to measure IO. But I just wanted to see when in the whole trace the actual physical write was being done. So it seems to me that, because the sysinfo:::pwrite is right at the end the performance bottle neck is more because of the locking etc.
The database files are on ufs filesystems. Is zfs better? Regards Hans-Peter -- This message posted from opensolaris.org _______________________________________________ dtrace-discuss mailing list dtrace-discuss@opensolaris.org
