Following the previous thread on the webmail system filer performance (I'm still collecting performance improvement hints) I would like to hear your opinion on NFSv2 versus NFSv3 on this scenario.
F7X0 and linux 2.4.18

I have run both v2 and v3 without issue or mishap with Solaris 8 and FreeBSD.
I didn't notice much improvement with either vs the other.
Why don't you try building a FreeBSD system and trying your server software on that and seeing if performance improves?

Given that you're using maildir, v2 may be preferable right off just to avoid the readdir+'s. Take a look for other tuning tips for doing a news spool over nfs, as the usage pattern should be comparable..
Take a look at Mark Crispin's rant on maildir-style drops in the c-client distro as well -- it may be well worth experimenting with different formats rather than going w/ the djb kneejerk.

Nopes, the måildir format is necessary to avoid the locks.
