Visual Basic Optimization

[ub3r_n00b]

Any clue on how to not make a loop in VB take up most of the CPU load? I dont actually think its my loops that are doing it - I think its writing to a file that is..

anyways..

any tips on optimizing vb code would be great, although I have read 10000 pages on how to do it already.

Disk writes are blocking. Are you buffering at all or opening the file and writing from within a loop?

writing to a file within a loop yes.. uses up a ****load of CPU

The sad part is it isn't 'using' your CPU...rather waiting to access it.

What type of hardware are you working with and how much data are you writing? How many times are you opening a new file handle, what is the frequency of disk writes from buffer?

sever with dual xeons (is what it will be running on) I am basically writing emails to .eml files from a POP3 client and then updating them to Outlook

Dual CPUs won't be too much help here - unless you are running other services on that box as well - as you can't write to two parts of a disk at once. Disk speed will be king as you aren't doing anything that requires significant math.

What type of hardware are you using now? How fast are the disks and what other services are you running? How is your memory usage looking while you are running your script?

I'm still a little confused about what you are trying to do (or maybe why). Are you trying to convert emails from a different client to outlook format or trying to send a batch of emails?

well actually the app doesnt take up much resources, and cpu usage is low on the server so I think we are good to go...
