I don't know how EC2 works in detail, but 5000 transactions per second sound impossible to write to disk. Even 500 are impossible if your disk doesn't have VERY fast access times. There was a similar thread on the sqlite mailing list, here are the most interesting posts: http://www.mail-archive.com/sqlite-us...@sqlite.org/msg42991.html http://www.mail-archive.com/sqlite-us...@sqlite.org/msg43105.html Judging from what people tell there (seems to make sense to me) your os does not perform proper transactions if they are much higher than 50. Or you have extremely fast hard disks. -Matthias _______________________________________________ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@zope.org https://mail.zope.org/mailman/listinfo/zodb-dev
