Yeah, UPX came in my mind too. I'm big fan of UPX and UPXed everything that was possible (also 1/2 of windows, etc.). On faster system (say some PII/PIII) I belive it's faster to load e.g. 1/3 of original exe file size and decompress it fast insteal loading big exe from relative slow HDD. As Lucho wrote NRV should decompress very fast and if it was not changed in last UPX the default algo is NRV (you need special option to enable LZMA). But I don't know how GCC 4.2.2 package was compressed. Is possible to alalyze compressed exe soume way to tell what compress was used? If it was LZMA the solution is repack it with NRV.
I'll try some bench later at evening.
