Anyone got good ideas? Jason, can you figure out what system calls are being performed at this time? Is it network re;lated, or filesystem related? Are there pthread related elements? Maybe a ktrace might give some clues.. (or a profile?) this has to be something really silly, because one order of magnitude is just ridiculous.. julian ---------- Forwarded message ---------- Date: Wed, 26 Aug 1998 00:12:20 -0700 From: Jason Venner <jason@idiom.com> To: julian@whistle.com Cc: hosler@lugs.org.sg Subject: Linux beats freebsd to death Note I just posted on the postgresql ports board. Either the K6-200 is the fastest machine on the earth or there is something seriously wrong with postgresql/jdbc and freebsd I have a couple of machines that I run postgres 6.3.2 on. Linux 2.0.32 K6-200 1meg cache, 128meg ram, scsi disks - fileserver/workstation/web server/dbms gcc - 2.7.2 FreeBSD 2.2.5-RELEASE P200 512k cache, 96meg ram, scsi - workstation/web server/dbms FreeBSD 2.2.7-RELEASE PII-333 512k cache, 256meg ram, scsi - web server/dbms I have a testsuite that creates a table and inserts a set bunch of rows. I try the table in autocomit on/off mode and rollback and commit it etc. to collect informatin. I am using the distributed jdbc driver as my interface. Under the linux machine it takes on the order of 2 seconds to do this on the 2.2.5 freebsd machine it takes on the order of 18 seconds on the 2.2.7 freebsd machine it takes on the order of 21 seconds To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
