M11X - Very high CPU usage copying files over wireless.

Hi folks,

I was wondering if this problem is unique to me or not. I'm connecting to my access point over 5GHZ wireless N, and whenever I do a file copy over the network my CPU gets pegged at 50-70 percent.

The reason this came to my attention is because I was trying to troubleshoot why sometimes my wireless transfers were so slow and network utilization was bottoming out to zero all the time, and sometimes things shot across at the normal 15-20MB/s the whole way. Turns out the times it was slow was when I was alt-tabbed out of Dragon Age which takes 100 percent of the CPU. (think this is a bug).

I've tried different drivers but not much else than that. Is this normal? Anyone else seeing this in a similar configuration?

 

I had a very similar problem with the M17x whenever I tried copying large files across either a Ethernet or Wireless.

The solution I found was that my Anti-Virus (Trend Micro) was on Network protection mode (Diffrent from firewall). Once I disabled this it worked as it should.

Hope its the same thing for you.. I know it annoyed me for a bit haha!

 

I think you may be onto something. I went ahead and disabled Windows Firewall and things mellowed out a slight bit. I still fear the usage is too high though, and if the CPU was doing anything remotely intensive the same dropouts would occur. I'll test it and report back.

I don't have any malware protection installed as yet, and anything I would put on wouldn't have anything that hooks into the networking.
