Hello, Would you please help me with this problem which I have been battling for more than a month. I installed Red Hat 7.3 on faster machines ( dual 2GHz) and the writing time to a SUN server (running Solaris 2.6) filesystem is almost 5 times slower than my 400MHz machine running some Red Hat 6.x (kernel 2.2.5-15), 10 times slower than a 1 GHz machine running Suse 7.3(kernel 2.4.4). I had tried changing rsize, wsize and got no significant changes, followed the instructions of the latest NFS FAQ (Section 5 about Performance Optimization). I tried the options "sync", the settting of rmem, maxmem, etc....). I also installed the new nfs utils package to the slow Linux NFS client machine. I heard RedHat version 7.3 is buggy and 7.2 is no problem. Thus I tried 7.2 and the latest 8.0 also. Still no change. All the machines are ext2 format, no firewall. I can not blame our network because all the machines are on the same network. I also have my "iotest" program (written in C) writes to a filesystem served by one of my dual 2GHz machine and running Red Hat 7.3 (i.e. RedHat 7.3 writing to RedHat 7.3). It's a little faster than writing to the SUN but not much (0:02:31 vs 0:02:51). Did anyone had this problem and got it fixed? I don't like the improvements which penalize performance drastically or demands so much time for getting the right configuration. Would getting the book about Linux NFS help me solve my problem? Thanks ahead for any help, Kathy Le - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
