<h1>Benchmark tester</h1>
<p>En liten sammenligning av hastigheter mellom Perl, Python og PHP. Husk at
programmeringsspråk som C++ og ML er i de fleste tilfeller flere hundre ganger
raskere enn både PHP, Perl og Python. Og for all del: ikke se deg blind på
hastigheter. Det er mye annet som spiller inn også. Som for eksempel
skrivbarhet, lesbarhet mm.</p>
