I read your previous posts and thought "another one who implemented
zlib compression for the TCP stream and failed to provide numbers". So
I didn't looked at the patch. Now looking in the current patch I see
that we both had indead the same idea. I avoided zlib compression till
now since I thing it can be done on top of the deltas
transparently. Also till now I didn't know a good way to merge the
packets in chunks (to yield better compression ratio). Using
PACKET_PROCESSING_{STARTED,FINISHED} is nice. Per will be pleased that
you produced a patch which only needs the cpp. Let me finish my delta2
and than we can compare features, performance and elegance.
