WrightMark - My new benchmark tool

[dig412]

I was experimenting with the WinBinder library for php, and i decided to make this tool.
It has 3 tests:
1. Timing loops for pure cpu speed
2. Making a large string for memory testing
3. Generating and writing a 300Mb file for cpu, memory and hard drive test.

The times are then aggregated into a score, and a hash of the score is made.
Lower scores are better!

Unfortunately the compiler i use doesn't support php5, so its half the speed it could run at.
Give it a go and see what you think. http://www.helixtech.org.uk/wrightmark.zip

Because its php it could easily be ported to Linux or Mac for a cli version.
