Try mounting with noac nfs mount option to disable attribute caching. ac / noac "Selects whether the client may cache file attributes. If neither option is specified (or if ac is specified), the client caches file attributes." -Rajat On Tue, Aug 14, 2012 at 3:51 PM, Mulyadi Santosa <mulyadi.santosa@gmail.com> wrote:

For now, /etc/export file has the following setting *(rw,sync,no_root_squash)
hm, AFAIK that means synchronous method is selected. So, theoritically, if there is no further data, the other end of NFS should just wait.
Are you using blocking or non blocking read, btw? Sorry, i am not really that good reading VFS code...
On client side we have not specified any options explicitly. This is from /proc/mounts entry
rw,vers=3,rsize=32768,wsize=32768,hard,proto=tcp,timeo=600,retrans=2,sec=sys
hm, not sure, maybe in your case, read and write buffer should be reduced so any new data should be transmitted ASAP. I was inspired by bufferbloat handling, but maybe I am wrong here somewhere....
