Actually, it appears that it is running rather smoothly at this time, with occassional hiccups. If anyone wants to help, reduce the number of posts and topics that you see per page and limit to view the posts that have been active only in last week or so. This can all be accessed through the My Home / Display Preferences. If you don't care about signatures, feel free to turn them off as well.
These improvements are small on the individual basis, but when you multiply it with couple of thousand people, it matters.
