Shutting off the USR and PM2 which is keeping customers happy is NOT a
reasonable response to paying customers!

The users are playing games on our Kali game server. They are seeing a
significant change in play performance when running on the PM3. So we
have almost no one on the PM3s and full PM2s.

When can I get it? When will it be out of Beta?

+ The V.42bis dictionary is 1/4 the size of say USR in the current code - on

The gamers see a difference. I guess these packets are highly compressable
as well, causing the problem.
