Effects of packetloss on the system.
-
I'm starting to notice a bit more packetloss than normal on these scorching hot days.
However I was not aware but it looks like at as much as 1% packetloss shoots my cpu up 10-20% in utilization.
It makes sense that it would if I were doing file transfers or under some sort of traffic load but the system is pretty much at idle.
Anyone have ideas on what im experiencing? The tech in me wants to throw more cpu at it but I'm trying to be reasonable.

Probably not the packetloss increasing CPU usage, but CPU usage creating packetloss. Check your system load. CPU usage should not be so bad as to cause loss in most cases. May want to make sure your CPU is not getting so hot that it's throttling itself.
-
I doubt whether there's any real diff in CPU usage, and it would take much more than 10% CPU usage to cause 1% loss. It'd have to be absolutely floored, pegged at 100% CPU, to have 1% loss.
Which process is using the CPU?

That's what's so confusing.

I did notice every once in a while some kind search command running as root. I figured it was a cron job for a service. -
That's basically idle. Any loss is likely attributable to a problem on your Internet connection. The processes you see coming and going are from updaterrd's stats gathering.
