Repeat the tests, but take a snapshot of v$sesstat for the session on each test. I would guess that you will find that there is a more than balancing difference in the statistic "buffer is pinned count" which also records accesses to buffered block, but uses a different buffer access mechanism.

Since in most case, higher consistent gets means longer time. There is no one else running on this server, And I also tested with event 10046 with no wait event.I tested for several times, with the same result. > Can someone help me understand it? > Thanks very much. > > > > >Regards >zhu chao >msn:[EMAIL PROTECTED] >www.cnoug.org(China Oracle User Group) > -- Please see the official ORACLE-L FAQ: http://www.orafaq.net -- Author: Jonathan Lewis INET: [EMAIL PROTECTED] Fat City Network Services -- 858-538-5051 http://www.fatcity.com San Diego, California -- Mailing list and web hosting services --------------------------------------------------------------------- To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB ORACLE-L (or the name of mailing list you want to be removed from).
