NFS mounted share read/write too slow

I have several NFS shares mounted as source folders and several as destination ones. File is taken from source, and with some changes put to destination. Making changes itself takes very short time, but read/write operations from/to NFS shares take extremely long time, e.g. 10MB are transferred for around 6 mins. Any ideas how to speed this process up?

Thanks in advance

On client tweaking NFS mount options might significantly improve performance.
I found that default rsize and wsize are too big and reducing their values helps. However testing would be the best way to determine optimal values for rsize and wsize in your environment. At the moment on gigabit network I'm using rsie=262144,wsize=262144 but this may not be ideal for you. Also noatime,nodiratime may help a little.
