A Tale of DXPC: Differential X Protocol Compression

When you have a slow modem and want faster transfer rates, data compression with this program is the answer.
Conclusion

The compression methods used by DXPC are compressions that cannot be done by hardware compression in the modem. In fact, I believe it complements other compression techniques to increase overall performance. The authors have done an excellent job of developing and maintaining a stable, easily compiled and easy to use program. I wish I had found it a year ago. Please note that if you use X authority with a .Xauthority file, some extra steps are necessary to use DXPC. These steps are covered in the README file distributed with the source.

Brian Pane informs me that they are preparing to release DXPC 3.6.0 soon. He has added compression for more X messages.
