In previous discussions of compression at level 4, several people correctly pointed that TCP-compression may reduce the number of IP packets while IP compression can only reduce the size of each packet. Fewer IP packets may enhance performance even more than utilizing compression history. But - and this may be a BIG implementation obstacle - the current compression algorithms require ~16KB of compression and decompression context for _each_ connection. In other words, 16KB per socket... Also, UDP is still a useful L4 protocol and no stateful compression is possible here either. Regards, avram
