Neither of these statements are true.

User home directories is one of the best things you can do with NFS. 
It's what it was designed to do after all.

Your performance problem is simple. Every Unix and Linux vendor in the 
world these days defaults to setting NFS write caching off. This makes 
NFS performance excruciatingly poor for lots of small writes, the kind 
of behavior you see when someone compiles lots of little C files. Enable 
write caching on the home directories and watch your performance improve 
dramatically.

Storing repositories on NAS has less to do with yes/no and more to do 
with how the code servers -- the servers that users check out and in 
through -- talk to NAS and what you've done (or not done) to optimize 
that performance.
