I notice this, too. It's takes a long time to post sometimes, even over my DSL connection.
It strikes me that the huge LatinPass threads take very long to post to, but other threads may not have the problem. There are so many duplicate posts there, likely because people hit "Submit" 3 or 4 times, thinking that their post didn't submit when in fact the server was just slow. If that's the case, maybe it's time to lock the LatinPass threads and start them over again.
