Currently msys2 installer uses 128MB dictionary and maximum level (9) of compression, which causes it to be quite slow and memory-hungry (up to 10+ GBs on my machine for compression).

It can be faster for both client and builder, but it gains additional 20% of size with -mx3 -md16m.

It's not particularly slow on Hydra, but all those 400MB files do use some disk space.

Maybe just use those flags locally.
