Can Linux Kernel 2.4.X handle two IP Packets at the same time
in a SMP machine which has two CPUs?
I have a SMP machine which equips two Intel Xeon CPUs and two
Intel Gigabit Network Cards. When I sent small IP Packets
to the machine, most of packets are dropped. When I watch
CPU utlization with TOP program, only one CPU shows high value
but the other shows much low value, ie. 10% CPU utlization.
My test shows current IP Stack in Linux Kernel cannot provide
SMP Processing properly. But, some articles said Linux Kernel 2.4
gives true SMP processing. What do you think my problem is?
I will be interested to hear if your tests can generate heavy traffic
for more than a few hours...my machine keeps crashing when doing this
kind of test.
How many packets are you trying to send?
Also, try loading the NIC with TxDescriptors=4096 RxDescriptors=1024
