NetBSD ported network drivers performance?

Hi,

I'm using iperf to test network NICs like realtek 8111G or Intel i82544 in QNX 6.5.0, and the performance cannot reach 
gigabyte level (Only 400~500 Mbps).   
When test with the same board&NICs in ubuntu or windows, it works properly (900+ Mbps).

I had downloaded both the latest devnp-rtl8169.so and devnp-e1000.so, but it doesn't improve the bandwidth.

Is there any possible to improve the networking performance?

Thanks & regards,

Hugh Brown

Re: NetBSD ported network drivers performance?

The Linux stack supports multiple threading, so that is why it is faster.
The current io-pkt only utilizes single threading.
