+ There is some strangeness going on here. It looks like algorithms
+ at the end take some kind of penalty. For example, running the RW tests
+ first got a result of:
+ RW-1024: 148.14 ms / private operation
+ but running them last output:
+ RW-1024: 363.54 ms / private operation
+
+ I think it's from memory fragmentation in the allocators, but I'm
+ not really sure. Need to investigate.
+
+ Until then, I've basically ordered the tests in order of most important
+ algorithms (RSA, DSA) to least important (NR, RW).
+
+ This strange behaviour does not seem to occur with DH (?)
+
+ To get more accurate runs, use --bench-algo (RSA|DSA|DH|ELG|NR); in this
+ case the distortion is less than 5%, which is good enough.
+
+ We do random keys with the DL schemes, since it's so easy and fast to
+ generate keys for them. For RSA and RW, we load the keys from a file. The
+ RSA keys are stored in a PKCS #8 structure, while RW is stored in a more
+ ad-hoc format (the RW algorithm has no assigned OID that I know of, so
+ there is no way to encode a RW key into a PKCS #8 structure).
