Re: [Dovecot] 1.0(.14) vs 1.1.2 performance

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 nfs attribute 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 code rewrite 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.
