Technological advancements are made. UDP Broadcast was completely broken in the 90s in Linux and was fixed by people in the finance industry. High speed network cards are constantly improving thanks to those same people.

It's a low pass filter. And I'm assuming the low-pass is used in the DAC to cut off high frequencies it cannot handle.

Calculating greeks is not very difficult and bandwidth is going to be the bottleneck due to the high number of inputs necessary to calculate them. So no wonder that CPUs outperforms GPUs. Also, real time calculation of greeks is very easily
