I happen to have an old POWER3 AIX box available. I got tired of waiting for a fsck --full to complete on the git repo, so I used git://anongit.freedesktop.org/git/xcb/libxcb instead. Best of five runs: OpenSSL: $ time ../git-1.6.4.1/git fsck --full real 0m4.120s user 0m3.776s sys 0m0.031s BLK_SHA1: $ time ../git-blk/git fsck --full real 0m4.231s user 0m3.867s sys 0m0.026s PPC_SHA1: CC ppc/sha1ppc.o Assembler: /tmp//ccdODWpe.s: line 8: 1252-142 Syntax error. /tmp//ccdODWpe.s: line 9: 1252-142 Syntax error.
