My situtation is that I have a NFS file server that gets data in bursts. The first couple of burst move quickly, but once the system memory becomes filled, mostly held in "cache", then my NFS performance drops. The issue here is how to get the VM to write out the data held within the cache when times are slow (which amounts to 90% of the time)? I have played a little bit with the /proc/sys/vm/dirty_ratio, etc with out much help. Any suggestions? Thank you for your valuable time. Phy Prabab __________________________________ Do you Yahoo!?
