Default Realtek eth card high CPU usage


Hi,

My problem is:
After installing the driver for Realtek RTL8169/8110 ethernet card, the
CPU Usage is up to 40-50%. However, there is no high process usage other
than idle. When disabling the network adapter, the cpu usage is down to
2-10%.
The OS is Win XP with SP3.

I've tried Process Explorer from
http://technet.microsoft.com/en-us/s.../bb896653.aspx. This one
showed that "Hardware Interrupts" are responsible for 50-70% CPU usage.

Then, I've used Kernrate to investigate further. It showed that two of
the modules are responsible for a lot of hardware interrupts:

hal 67%: Windows Hardware Abstraction Layer
rtnicxp 26%: Realtek driver for RTL8139/810X family fast ethernet
network card

I've tried to update the driver for the adapter but with no results.

Any help will be appreciated.

Thanx,
Adrian
