Upload codes problem

[ADesigner]

hi all,I try to write some codes for upload files:
what I used is
vbscript
ado.stream
fso

but,I saw that CPU is 90% when I was testing the codes,so can you help me or tell me how to write the codes about upload files or where i need to change in my codes ?:confused:

Welcome to DP, Adesigner. A few things that will help our members help you:

Clarify things a bit - i.e. did your code do what you expected it to do, or did it error out? Also, what is your code? It's hard to diagnose what might/might not have gone wrong if all we know are the elements you chose to use, but if you provide us with some code samples, we might just be able to help you improve your code.

Are you using a third-party upload script, such as aspupload? or are you trying to write your own upload script? Are you trying to upload images, text files, audio, or what? What file size are these items you are trying to upload? Also, by saying CPU is 90%, are you referring to your client-side CPU, or the server CPU? Either way, what services are eating up your CPU usage at the time?

For starters, answer these questions, and provide code, and we'll see what we can do to help ya out.

Again, welcome to DP!!

yes,I'm sorry for that,so,here is my codes,they can run exactly,
but the latency time is so long(almost 30 min) and the program impropriate the cpu resource more than 70% when i run the codes to upload 3 files (size:1st is 10M,2nd is 8.4M,3th is 43.3M) ,

SO WHAT I NEED is how can i improve the efficiency of the codes!

My Codes:

well, Is my arithmetic not good or there's some way more better? I really don't know how should i do to improving my codes,

help!
