Re: FreeBSD filesystem performance in Enterprise
FFS is fine, until you crash. Generally a FreeBSD machine with FFS and Softdeps can keep up, the challenge comes when you have to fsck everything to get back from a crash. That is why things like LFS et alia are useful. For things like mail directories the problem can be partitioned into dozens or thousands of nodes. Yahoo uses NetApp filers for this. How many filesystem ops/second? Generally it will constrain how many emails a day you process at some level. Will it work? Sure, it will work fine. And on a RAID system it will be unlikely to corrupt data, and with a file system mirror you will be unlikely to lose data. --Chuck ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

You are almost starting a holy war :) I believe hotmail used to be hosted on FreeBSD until it was bought out by MS, that should be a decent volume indicator. I run a very small email list server and it works fine on a p200. I did see a noticable jump in speed when I switched the mail service from sendmail to qmail, so it is also dependant on what you will run. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
