I wonder who would be able to compress the contents of the archive linked below (extracted into 100MB a *.arc file!) to a size smaller than 30MB or 30000KB... 25MB or less would not be bad. (Although, would it be of any practical use, in addition to benchmarking, to the given compressor/archiver if it is not capable of decompressing at a speed of 5-10+ MB/s.)
Compression (last v22c4b): lolz_x64.exe -dt -d64 -fba4096 -mc1023
Whatever you can use, you can start with the PAQ family.*

Decompressing use: cls-lolz_x64/86.exe TEST0.lolz TEST0.arc
*Note: FP8_v6 or LPAQ or MCM not better than LOLZ, 5-10% ratio less.
Question: Is there an asymmetric CM compressor?
