Hi,
I am writing a simple sniffer program that will
sniff packets in a gigabit network. I am using a dual
processor 2 GHz Xeon processor with one Intel Pro-1000
desktop adapter, running 2.4.20-8smp linux.
I found that for all packet sizes and network
bandwidth, 2.4.20-8 uniprocessor version that uses
only one processor is performing better than
2.4.20-8smp using two processors in terms of packet
drops and CPU utilization. Each processor in smp is
utilizing more CPU than one processor in uni-processor
case. What is the reason for this peculiar behaviour?
Is it possible for me to use the power of second
processor without adding more NICs. Will I face
similar problems with 2.6 also? Anybody familiar with
these please help me out.
TIA
Satya Srikanth
