Like others I am having issues getting any decent performance out of my NFS= clients on FreeBSD.I have tried 8.3 and 9.1 beta on stand alone servers or= as vmware clients. Used 1 Gig connections or a 10 Gig connection.Tried mou= nting using Version 3 and Version 4.I have tried the noatime=2C sync=2C and= tcp options nothing seems to help.I am connecting to a IceWeb NAS. My perf= ormance with DD is 60 meg a second at best when writing to the server. If I= load a Redhat Linux server on the same hardware using the same connection = my write performance is about 340 Meg a second.=20 It really falls apart when I run a test script where I create a 100 folders= then create a 100 files in the folders and append to these files 5 times u= sing 5 random files. I am trying to simulate a IMAP email server. If I run = the script on my local mirror drives it takes about a one minute and thirty= seconds to complete. If I run the script on the NFS mounted drives it take= s hours to complete. With my Linux install on the same hardware this NFS mo= unted script takes about 4 minutes.=20 Google is tired of me asking the same question over and over. So if anyone = would be so kind as to point out some kernel or system tweaks to get me pas= sed my NFS issues that would be greatly appreciated. Wayne =
