I will run tests on a local box but I cant be toggling the kernels on my production servers.
Thanks

Hi Chris,
So have you removed the QUOTA feature from your production boxes? I am curious what you did here to get things working on the stable 6.2?
I am amazed more people are not having an issue with this.
Thanks
Paul
no I use QUOTA but put up with the performance hit, all my production servers are dual core now and new ones will be core 2 duos so I work round it with raw power, also using SATA hds instead of PATA. I dont use QUOTA on every single server tho, just the commercial web servers.
Chris
Thanks for your reply.
That is odd as I used two Dual Core CPUS (4 in total) XEON 64 with 16 GIG of RAM and SATA HD on the amd64 branch with a very fast Areca controller and the hit was so bad that the system was not usable at all. It was like going back to a 386 (or beyond that).
Did you provide any mail services on that server? I have a hunch it was the multiple instant access to many files that was causing the slowdown (50-100 of small file reads and writes per second). If you only provided FTP type access then that may not have been as big of an issue as you may not have had as many concurrent file writes.
Thanks
Paul
