can someone test bwt based compressors (eg. dark) with big block size? matt on ltcb for unknown reason uses block sizes that are 1/2 1/3 1/4 of enwik9 size instead of using max possible dictionary size (block size should be maximal unless file isn't homogenous, in such cases it should be divided to maximal homogenous blocks).

i tried testing dark but it failed.

That's because Dark v0.51 with p-b390mf give error "Not enough memory!"

There is only 2GB memory in test system.

big block size
5N is too much for his testing system :) BBB should, on the other hand, handle whole enwik9 even on 2GB system.
