Hi guys,

I wondered how fast Memblocks and Arrays are when being created, having large values written to them and being read again, so I threw together a program to test this.

//memblock vs Array
/*

It is the goal of this program to test the creation speed, data write, and data read of memblocks vs arrays when writing integers

this program works in 3 stages

1) creation
2) write
3) read

// timer setup

If you have any suggestions for improvement, or see any problems with my methods please feel free to comment. I\'m also running these on various hardware to see the difference in memory performance.

I completely misread my own results before, so I've compiled them into a bar chart for easier comparison.

So in conclusion, if you want to speed up your program, try using memblocks for bytes and floats. It will work better if you have any intensive read/write memory operations going using those types.

If you are using integer's then arrays appear to be slightly faster for read and write operations but are still much slower when creating them.

When you edited your post, your code got messed up. It added escape characters everywhere you had quotes for your strings. I fixed it.
