For some reason, your newly compiled version performs much worse for me. It is about 75 to 80% slower on all options (Deflate, LZMA, BZIP2) than the previous 9.13 compile (Did you compile without FPU support, or ???). Also, although it does not overtly crash on the same data that the other one did, on -mx9 and .7z LZMA data, the program just 'halts' at the place where it otherwise crashed before. I must manually Ctrl-Break, or Ctrl-C out of the program. Otherwise it just hangs forever! Very strange. This is on my 1gb system, running MS-DOS 7.1, CWSDPMI r7 (and r5, too). I just tried FreeDOS 2038 and get the same behaviour. Also, the same using HX-Extender. although it merely crashes as before, instead of hanging, but it's still at least 50% slower than your other 9.13 compile.
