I am looking for a file upload ,but I don’t know which one is fit for me , I hope

some one who using the upload tools can give me some advice ,thanks.

I prefer the tools would like this :

1.Easy to use ,hi-performance-aspfile upload component.

2.Fast and optimized for speed,uses low CPU cycles.

3.Support for Unicode filed data and filenames .

4.The price is in reason.
