RE: stress in network when connecting the router to the internet



Hi eran,
All routes and firewall operations are done in kernel memory so there should be any disk access.
The more likely candidate would be some daemon or a user running a process.
use ps -ax to see what unnecessary processes are running and eliminate them.
Another problem could be that your h.d uses PIO instead of DMA access on the ide controller.
A PIO would mean that the kernel request data relying heavily on interrupts, while dma should be used for h.d data transfers.
do 'dmesg|more' and see how your kernel identifies the h.d access.

Subject: stress in network when connecting the router to the internet


Hi,
Maybe its easy to answer, but I cant find the answer for this:
When I connect my router to the internet my server getting into load, 
stress. The server start to proclaim voices of Tractor from the disks. We 
have antivirus in the server, but the last admin didnt install antivirus in 
all computers in the labs. Can it be a virus? any idea?
