While the new v2 client claims to be supersparc-optimized it even
performs less fast on an SS 20 ('cpu0 is a "Model 71 SuperSPARC-II
SPARCmodule" CPU') over here.
These are the results when I benchmark the clients:
bash$ ./rc5-solaris-supersparc -m
rc5-56-client: Performance testing with 1000000 crypts
rc5-56-client: Complete in 12.390 seconds. (80709.57 keys/sec)
bash$ ./rc5v2/rc5v2-supersparc -benchmark

Benchmarking with 10000000 tests:
Complete in 138.589 seconds. [72155.89 keys/sec]
On a ss5 it does indeed perform a lot worse too. About 25%. I get about
29K with v2 and 40K with v1.
