There is a massive (3-18x) slowdown when re-querying a large nfs dir (2k+ entries) using a simple ls -l. On 2.6.23 client and server running userland rpc.nfs.V2: first try: time -p ls -l <2k+ entry dir> in ~2.5sec more tries: time -p ls -l <2k+ entry dir> in ~8sec first try: time -p ls -l <5k+ entry dir> in ~9sec more tries: time -p ls -l <5k+ entry dir> in ~180sec On 2.6.23 client and 2.4.31 server running userland rpc.nfs.V2: first try: time -p ls -l <2k+ entry dir> in ~2.5sec more tries: time -p ls -l <2k+ entry dir> in ~7sec first try: time -p ls -l <5k+ entry dir> in ~8sec more tries: time -p ls -l <5k+ entry dir> in ~43sec Remounting the nfs-dir on the client resets the problem. Any ideas?
