ACK, you think you fix something. Okay.
The client should be version 1.75-13 if it isn't, you'll need to refresh it at some point.
The server should also be version 1.75-13. Be n the look out for both of these when you start playing in the message bar.

I made a little new update that fixes the slowdown and I think may finally fix the lockup that sometimes happens with discarding.
