Seems to be a good benchmark for executable, embedded image and audio. Precomp doesn't detect anything even in brute mode (except one small false positive).
Interestingly, paq8px (v111, a bit old) detects a 123 KB JPG in PariahInterface.utx (offset 1001499 - 10138778 ), this is a false positive (see attachment). Also, it doesn't seem to detect the .wav correctly. It detects all of the executables though.
So, some results with Precomp and paqpx compared to the RAR, just because I was curious
Test system is a DELL E6540, 4 cores + HT @ 2.7 GHz, SSD
Code:
RAR 39.925.276 Bytes
7-Zip Store + Precomp 0.4.6 44.724.634 Bytes - 28 s // nothing detected, so this is just basic LZMA2
7-Zip Store + Precomp 0.4.6 -lt1 44.266.262 Bytes - 60 s // 1 thread instead of 8
paq8px_v111 -3 38.022.601 Bytes - 14 min
paq8px_v111 -4 31.172.781 Bytes - 119 min
