Terminal C can be pretty bad, if your flight is leaving form C8, C9 or C10 security won't be that bad as there's only 3 gates in that wing, though with only 3 gates there's not much for food options if you need a bite before departing.
If you are departing from the main portion of Terminal C then I'd allow for at least an hour.

The Massport terminal map shows they are connected, thus I would assume access is via the main C checkpoint (which has the disadvantage of long lines, but the advantage that you have access to all of C (except for the C40-42 area).

C8-C10 are accessed through the main checkpoint just like the rest of the B6's gates. They do not have their own checkpoint like C40-42.
