As soon as I mount my NFS file systems, the network load increases to a constant 80%-90% of network bandwidth, even when the file systems are not in use. NFS stats on the client machine (nfsstat -c) produce the following: Client Info: Rpc Counts: Getattr Setattr Lookup Readlink Read Write Create Remove 0 0 8 0 0 0 0 0 Rename Link Symlink Mkdir Rmdir Readdir RdirPlus Access 0 0 0 0 0 1 0 4 Mknod Fsstat Fsinfo PathConf Commit 0 73030 6 0 0 Rpc Info: TimedOut Invalid X Replies Retries Requests 0 0 0 0 73049 Cache Info: Attr Hits Misses Lkup Hits Misses BioR Hits Misses BioW Hits Misses 37 1 10 8 0 0 0 0 BioRLHits Misses BioD Hits Misses DirE Hits Misses 0 0 1 1 1 0 Fsstat and Requests are increasing very rapidly. Both the client and server are i386 5.4-STABLE machines.

Is this behaviour normal?Sort of. Some fancy parts of X like file-manager/exporer applications tend to call fstat() a lot, but it's probably tunable, and if you enable NFS attribute caching that will help a lot. "ls /afs", if available, is a wonderful test of whether a program/file-manager is being polite. Anyway, "top -mio" is likely to be informative. -- -Chuck
