Yes I am user reiserFS on the AutoCad Shares (Jerry, are you?) The older machine is running ext3.
The CPU usage goes up, but I definately wouldn't call it a spike. It goes to about 1% which is probably normal. I did use the nolargeio=1 option and it did increase performance.. but.. I tried timing the time it takes to save. It takes the older machine about 1.25 seconds to save a 606KB drawing and it takes ~3 seconds for the new "fancy" machine. Could this be due to ReiserFS? ----- Original Message ----- From: "Rashkae" <[EMAIL PROTECTED]> To: "Brian Merrell" <[EMAIL PROTECTED]> Cc: <[EMAIL PROTECTED]> Sent: Wednesday, June 09, 2004 7:56 AM Subject: Re: [Samba] Samba just Slow with AutoCad? > Hi. > > Does your new system use ReiserFS? > > When these ~20 second delays happen, can you see if there's a spike of > System CPU time useage on the server? > > I've not heard of it happening over a network share, but some "poorly > behaved" applications can trigger a 'feature', (actually, a > performance optimization) with ReiserFS on Newer (2.6) kernels that > will make the kernel spin it's wheels for a number of seconds.
