We've had pretty good performance from NFS except when we start to put a
lot of files on them. Beyond about 50,000 files in an NFS directory the
performance of the target file system starts to bog badly. We've pretty
well determined this is a function of the target file system checking
for duplicate names in the directory and has nothing to do with iOS.

Would you mind sharing the full mount command you use? I'm wondering if there are some parameters that you have set that improve performance.

if you want to understand why that is, there are many good books on
the design of operating systems. please pass them along to redmond
when you're done reading them :)
