Hi all, I recently upgraded a number of NFS clients from SL 4.2 to SL 5.1. The NFS server is still running SL 4.2. Clients are acting very slow, e.g. - after SSH authentication, it takes about 5 sec. for the console prompt to appear - every 'ls' is slow - compiling stuff is terribly slow It seems to have something to do with NFS - I'm having some NFS-mounted directories in my $PATH (TC shell). When I throw them out, everything is working as expected (e.g. compiling gcc was ~9 times faster). Please note, that the same $PATH does not noticeably slow things down on the old 4.2 systems. I did comparisons compiling gcc on the old and new systems while running tcpdump. I found, that the new systems performed a lot more NFS lookups (by factor ~4). Everything else seemed normal. File transfer to the NFS server is OK, no speed problems here. Tcpdump, however shows a lot of lines like this one, when copying files: 18:19:56.571906 IP bsnode02.0 > morphin.nfs: 1448 null Load on the NFS server is much higher than before. I'm a little bit at a loss - how could I debug these issues further? Regards, Jan
