you should look inside these tests, as i done :)

most of these tests depends on libraries speed. in one test, PHP is
1st. from 2 or 3 tests that depends on compiler speed, one was fooled
by adding special function readInt to ghc libs and the rest are
written in low-level haskell code - look the sources

i'm sorry, but this test only shows amount of work spent to optimize
these programs. results of some tests was made 10-100 times better,
while improving real programs performance needs much more work :)
