milliseconds? We are in the nanosecond now. 10-20ns round trip on 10G or 25G card, in a server which is in the next room of NASDAQ servers to minimize transfer time. Doing millions of transactions per second.
When a packet is received on the RX line, decoded byte per byte (yes, at 25GBps), a packet is sent at the same time on the TX line byte per byte, when the RX byte with the price is decoded, the FPGA determine if you should sell/buy and send the TX byte accordingly on the bus. This takes nanoseconds.
I don’t actually work in that space, so I was being conservative with my scales, but I figured it’d be something like that. I didn’t know they were doing it on FPGAs now though!

It’s disgusting to me that we’re wasting this kind of computational power, as a species, for generating wealth instead of science.
That’s nothing compared to the useless calculations that are powering the shitcoins
aren’t they adding delay lines, so everyone has the exact physical cable distance to the stock servers?
For a while they were keeping microwave towers running to facilitate quicker transmissions. But I’m not sure what the current state is.
