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.
[same error repeated 42 times]
gmake: *** [ppc/sha1ppc.o] Error 1

Hmm. So that may not help so much after all. Let me know if there are any other tests you would like me to run.

This machine has: $ gcc --version gcc (GCC) 3.3.2

$ as -v as V5.3

$ lsattr -E -l proc0 frequency 200000000 Processor Speed False smt_enabled false Processor SMT enabled False smt_threads 0 Processor SMT threads False state enable Processor state False type PowerPC_POWER3 Processor type False
