Well, I compared the new 4.57 compile with the old one: it seems a good amount faster (esp. on my 486, but 586 also showed some little increase). So, if you can afford the extra .EXE bloat, it's worth the "upgrade", IMO. (Still a bit slower than Win32's 7ZA + HX though, heh.)

EDIT: Try "oldp7zip b -md20" and then "p7zip b -md20" and see for yourself. Even my newer cpus show that it's faster. (Kudos, Michael!)

EDIT#2: Oops, forgot to mention: 486 is much slower running .EXEs with UPX's LZMA-packing, so it will be much much faster if you unpack ("upx -d") and repack ("upx --best") on a newer machine first. This is what I did (else you might wonder why it's seemingly slower!). Of course, I'm probably one of only a few still (crazily? muahahaha!) using such dinosaurs.
