I just switched from dovecot-1.0.14 to dovecot-1.1.2 and noticed a significant drop in the server load average (which has become lower and above all doesn't seem to have unexplained peaks). Indexes are still locally stored and nfsattribute caching is still off).I searched the list archives for an explanation of what changed in the code that could explain such an improvement but mostly (except maybe some index coderewrite mentions) found differences in features. Where does that performance gap come from ?
Do you use POP3? That should work better. There are also less reads/ writes to index files. And dovecot-uidlist is usually updated by appending to it instead of rewriting it.
