Don't use async on the server unless you completely trust it to never crash or your data is not important.
I have to revisit NFS over Infiniband but I have definitely seen better than 40MB/s - is that maybe your disk subsystems limit rather than the network? How is your disk subsystem configured?

I'm also using the Infiniband now instead of the GigE and I've increased my default TCP window up to 6MB. None of it makes a difference. It's still around 40MB/s. Thanks for the thought.
