Please elaborate? Either the memory is used for a block cache or for the
program.
I'm interested now in seeing how the full history compression goes,
though. If it can achieve 70, 80, 90% on top of zlib, then it might
be worth embedding the compression as opposed to just using it for
transfer over the Internet.
The dictionary is compressed per block, so it greatly depends if the trick
works.
32 megs is a lot better than 900K, though. 900K is how much zlib uses, right?
I don't get your point here, what do you mean? Do you mean that the memory
requirements for zlib is lower? Because don't forget that the extracted
piece is kept in memory + the deserialised version. Which is basically
much bigger right?
