[OpenAFS] Tuning recommendations for latency between client and server?

At our site we've been beta testing some compute resources which
are available in the cloud - as part of that we're using/testing
our normal afs client  in the cloud - which is approximately 43 ms
away from our AFS servers.

Does anyone have client/server tuning tips which might help
improve throughput/performance of OpenAFS due to the high latency?

We have a 10 Gb network to the cloud but am seeing about 1 MB/sec
uncached read/write performance from clients in the cloud.

Any thoughts/recommendations welcome!
