On my bridge with 4 network interfaces, the additional latency is always below 0.5 ms, even if I'm pushing 400 MBit/s through the machine and a kernel compile is running at 100% CPU. Network interfaces are PCIe GBit from Syskonnect, the machine is an Athlon64 at 2 GHz. Even if the clock speed is halved by powersave the additional latency will not go above 0.9 ms. Kernel is vanilla 2.6.11.x.
