Thread-topic: Iperf Performance

When I run Iperf with an I/O buffer size of about 64 bytes (-l 64) and 1 TCP stream, the CPU remains almost idle (99%-100%) and I get a BW of about 90Mbytes/sec (1GB link).

Is there a way to use the CPU more efficient thereby driving more throughput?

I get very good performance (~940Mbytes/sec) for larger I/O buffer sizes.

Thanks in advance for the help,

-Sam
