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
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.
