Forgot to make this high priority/severity. This is really critical as I am going to have to stop using my Linux workstation and go back to Windows and smb to get acceptible peformance from our Linux file server. Linux-smb-Linux does not work for mounting home directories. Permissions, file name case, and dot files are all messed up. You have to use nfs not smb for home directories. Are you running knfsd? We do not see this kind of performance degradation here in the office. ------- Email Received From Bill Chatfield <bill.chatfield> 06/29/99 11:09 ------- I do believe we are running knfsd because lsmod says I have an nfs kernel module loaded. I would be happy to provide telnet access to a Red Hat person so you could see the problem where it is happening. Just let me know. BTW: Going back to using Windows was a threat I couldn't live up to. The NFS is slow, but it should not be that painfully slow. What is the size of the file you are dealing with? On a related thing, Samba can be instrumented to preserve the case for filenames, it just does not do it by default. On a 100mbit network the NFS server will peak at about 1.9MB/sec, while ftp is able to go up to 5 or 6 MB/sec, so dependong on the type of transfers that you are doing you will see the type of slowdown that you are talking about. I originally thought the machines in question were on the same physical subnet, but after physically tracing the ethernet wires, it appears that they are not. I suspect that this is the cause of the slowness. Does that make sense? |
