Today I additionally tried to compress whole game of 22gb(18gb after srep) with lolz to see effect of certain parameters:
Code:
+lolz:mt4 >> 8.98gb
+lolz:mt4:tt1:mc32:mtt1 >> 9.07gb
+lolz:mt4:tt1:mc32:mtt1:dto0:cm0 >> 9.49gb
Additionally I tried to decompress them, all of them expressed approximately same decompression speed and disk was limiting me. Clearly, do not disable context modeling, it have a good ~5% impact and doesnt slow down in neither compression nor decompression too much. Going from default to "-tt1 -mc32 -mtt1" had only 1% difference, in other words it is ok to lower tt# to 1 for speed and *especially* it is good idea to use -mtt1 which give you decompression # cores option without limit = future proof.
