Well, the night phase should always be very quick, unless day ends in an odd hour for some time zones. Individual night actions should take seconds to make and the mafia does not need several hours do determine a kill. Shortening the day phase during later stages may be good but it can't be too short since we have a lot of members on very different schedules and everyone should have a chance to participate. What bugs me more is when there is a consensus on who people will be voting for and we just leave the day open until the time limit to see if anyone decides to hang themselves with the time left or if some mafia on the chopping block slips up and outs their comrades.
The slowness really boils down to fewer number of players in the late stages who still may be in different time zones. Not really much we can do about that I think.
