Some people has asked me if it's possible to use pynfs for performance and/or load testing. The short answer is that pynfs is not very well suitable for this, because it has high latency. The reason for the high latency is partly the choice of Python as programming language and partly the heavy use of classes and instances.
But, by sending RPC calls i paralell, just like most NFS clients does, speed can be increased. Further, it's possible to hand-code certain tasks that needs to be fast.
