High CPU usage with Orinoco Gold, normal?
I've found when downloading at ~2mbit CPU levels average as high as 40%.

Is this normal behaviour when using 128bit encryption?

I'm using the latest drivers/firmware and Win XP SP2. Only suspect factor could be the Texas Instruments PCI adaptor.

Does this have anything to do with Netstumbler?

Yes, no, maybe?

Not knowing anything about the hardware in front of your card (other than the PCI adapter) would make any answer a SWAG at best.

Using any encryption adds overhead to the process.

Gee thanks for the informative reply.

This is a problem pertaining TO Windows so therefore I deem it to be in the appropriate section.

If not, move it. I don't need to read your rhetoric.

It's a PC. I wouldn't have thought hardware differences matter much beyond the PCI lane. It either works correctly or doesn't. I merely wanted to know if this is unheard of behaviour and worth investigating.

And it can be spelt either adapter/adaptor.

You'll read what ever I post because you're a slag.


If you have problems with Windows installed on a PC then you need to ask in the forum that deals with your Card or OS. I did not see anything in your OP that suggests you are asking about Netstumbler.

The area that you are posting to falls under the area of:

Quote:
Software
Discussion forum for non-Netstumbler wireless auditing or wireless related software
which I do not see, again, what is relivant from your original post:

So now, why would we be the ones to figure out your problem with high CPU usage when you are downloading whatever crap you are downloading?

If you don't like it, then sod off. (figured you might understand this part)

No that's not the only suspect matter.
1. You're possibly using a card that was not certified for Windows XP
2. You're possibly using drivers that were no certified for Windows XP
3. You're possibly taxing hard-drive write/caching speed
4. You're possibly taxing your CPU's ability to process data
5. You're possibly taxing other aspects of your system that you do not yet know about

You will to quantify and qualify using a number of system tests and procedures to validate your issue. This includes but is not limited to different drivers, different software to process the download, different tweaks to the TCP/IP stack parameters, another identical machine, a different machine with matching specs, a different card on the same connection and adapter.

If you not willing to run the test necessary which could take weeks to perform then live it. 40% cpu is not that bad. BTW, what makes you suspect the PCI adapter in the first place?

With my Gateway 600ygr p4 1.4ghz laptop,with XP SP2, running a Cisco aironet 350 series pcmcia card with 128 bit encryption. I generally get roughly about 4-5mbps which taxes my cpu at between 70%-80%.

So 40% cpu time looks pretty good to me considering I noticed no difference in cpu time with or without wep. The only change I saw was that download speeds increased slightly, not worth running unsecured however.

You have a real attitude problem.

I've been a member of this forum years longer than you, and let me state when it originally started it was here to help diagnose problems relating to wireless networking, as well as Netstumbler.

Obviously it's changed since, but that's no excuse to come over all arrogant and self-important. You are just showing yourself up for the dimwit low-life individual you really are.
