What stock kernel?

No optimizations? (-O0? )

No optimized glibc either?

I'd say that in both cases a competent benchmarketeer would be able to 
suggest tests that will provide results proving "his" side s the clear

/dev/random also gives me pure numbers :-)

Please suggest a test environment if you think it is so easy to come up
