Is there a reason why bridging in linux is not faster than routing?
It is faster, but not very much so.
The main overhead seem to be elsewhere, mainly hardware related (interrupt
handling, NIC driver, FSB bandwidth, PCI bandwidth and latency).
For best bridge performance make sure your kernel is NOT built with
support for bridge firewalling. The bridge firewalling support adds a fair
bit of overhead to bridgeing even if not used.
