I reinstalled the netperf to make sure its the latest.
I have also decided to upgrade Server-C (the i386 5.4 box) to 6.0RC1 and
noticed it gave a large improvement of network performance with a SMP
kernel.
As with the network setup ( A --- B --- C ) with server B being the
gateway, doing a basic 'fetch' from the gateway (B) to the Apache server
(C) it gives up to 700mbits/sec transfer performance, doing a fetch from
server A thus going through the gateway gives slower but still decent
performance of up to 400mbits/sec.
Are you by any chance using PCI NIC's? PCI Bus is limited to somewhere around 1
Gbit/s.
So if you consider;
Theoretical maxium = ( 1Gbps - pci_overhead )
The 4 ethernet ports on the Dell server are all built-in so I am
assuming they are on the best bus available.
