-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, I dont think this kind of test could have any meaning, given that table creation time doesnt import in any way. ... but I was curious, so I made the test :) >>Also, can we beat his estimate of 27 hours for creation? We would need his complete machine specs to be sure we can beat him. > for i in `seq 1 1000000`; > do > echo "create table test$i (ts timestamp);"|psql tabletorture; > done Just tried that script (still running) on a Dell PowerEdge 2800 (not my prefered, but only one I could use for that test...) 2 physical CPUS in ht: Intel(R) Xeon(TM) CPU 3.00GHz with 2m cache 2Gb ram Builtin Perc4, with Raid 5 and 5+1 10Krpm disks Linux ***** 2.4.27-2-686-smp #1 SMP Wed Aug 17 10:05:21 UTC 2005 i686 GNU/Linux I can send more details if you want (postgresql.conf..) > Now I got ~2600 tables in 4 minutes, so it might take a day to get the > million. However, the MySQL-guy has no statements about his > test-machine, so it's not comparable. I got a rate of 12 tables created per second (fluctuating from 10 to 13 so thats an approximation I do, Ill get final results on the end). So at the moment I'll have 1M table in about 23 hours on that server. I'll send complete results when it will be finished. - -- Jean-Paul Argudo www.PostgreSQLFr.org www.dalibo.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFED+9anDfYiZOkHKQRAgkSAJ0SUM5GfouYbushribtHPzGtfWBPQCffWNc 4vwrAr9z8p+8AAqL2ndFlP4= =bX5g -----END PGP SIGNATURE-----
