I operate my own Cyrus-IMAP server on a Linode [a VPS service] and use
Evolution for both mail and CalDAV with that server [CalDAV provided by
OpenGroupware Coils].  Evolution is running almost 24/7 and I use it
constantly for ~50 hours a week.  I don't even come close to that amount
of traffic.

It will cause a surge in traffic for initial synchronization -
essentially like POPing the entire folder.

Something is screwed up [maybe because gmail provides crappy IMAP
support?].  

Are you using server type "IMAP" or "IMAP+"? [Use IMAP+]

Do you perhaps have check-for-new-messages-in-all-folders enabled?
[Disable it]

Is "Use IDLE if server supports it" checked? [Enable it - assuming gmail
supports it]
