#     Makefile: use smaller dictionary size for xz module compression
#     
#     By default, xz without parameters uses a dictionary size of 8 MB.
#     However, most modules are much smaller than that.
#     The xz manpage states that 'increasing dictionary size usually improves
#     compression ratio, but a dictionary bigger than the uncompressed file
#     is waste of memory'.
#     Use a dictionary size of 2 MB for module compression, resulting in
#     slightly higher compression speed while still maintaining a good
#     compression ratio.
