LZMA Question
I have noticed that the lzma compression is quite slow when compressing even a fairly small installer. It nice and fast when uncompressing just the compression seems a little sluggish. Note sure if its a problem or just th design of the lzma algorithm.

the algorithm is definitely slower than zip or bz2.

It could be even slower than rar, but I am not sure.

All this tested with 7-zip, which is also very fast uncompressing.

Why is the speed while building the installer a problem? You only build it a few times before you ship it. As long as it's not slow to decompress, I don't see any trouble, really. Correct me if I've missed something, though.

Its not really a problem its just that if the oinstaller takes a while to build you are not sure if its still working or if it has died on you, especially on slower machines.

LZMA can have big problems to compress if you don't have RAM enough.

You can check the installer size as it builds for a minimal progress report.
