I don't know enought about Dovecot in particular to say whether or not
the speed is _purely_ the result of caching (and being written in C).
But I can state a couple of reasons why the server-side cache helps.
Keep in mind that IMAP is specifically designed as a clieng/server
protocol. I generally have the same mailbox open from three computers:
my home, my work and my laptop. When changes are made from one of these,
the other two need to get synchronized. Like most people, I try to
keep my mails organized into folders that don't get too big, but I still
end up with 1000s of mails in each folder.
Dovecot keeping a cache/index on the server side allows Dovecot to quickly
provide information when the clients want to sync up. When a mail client
is first started, it needs to do the equivalent of "send me a list of all
the emails in this folder". If Dovecot needs to scan each and every message,
it can be pretty slow, but if it has an index maintained that it can more
or less just ship as is, that's much faster. How often these types of
"overall sync" operations occur under normal usage, I don't know.
While I'm not an expert, I believe that Courier maintains indexes as well.
