Kernel bypass is also common. Having the OS manage your networking stack adds too much latency.

That is the most common one I've heard of.

Obviously if they are building fpgas into the switch itself then well of course they'd already tried running customized ethernet driver firmware and all.

It really depends on what asset class you are trading, like the author mentioned. For equities the performance demands are out of control (< 50 micros). For FX, it's still pretty tight but much more manageable.
