Hi,
I have a PCMCIA Lucent Avaya Communication Silver 11Mbps wireless card
(hosted on a PCI PC Card bus) installed on a gateway with a Pentium
233Mhz MMX CPU and this card eats all CPU at about 3Mbps (with >90% of
the time spent in interrupts).
The strange thing is that it doesn't really generate that many
interrupts (about 100 interrupts per second, versus ~300 total
interrupts per second). The card is attached (through the pccardd
daemon) as a wi0 interface and has WEP encription (40bit key) enabled.
My hypothesis is that the CPU is hogged by the WEP encryption
calculations done by the driver in the interrupt handler or it might be
something wrong with the driver.
Has anyone seen this issue ? Is it normal ? Could a better CPU (e.g.
700Mh Duron) handle the whole 11Mbps bandwidth ?
Some background:
