I don’t have any statistics but I have an anecdote.
I built a trading platform ~6 years ago that had a 100 microsecond tick to trade (a term that means from the time a market update hits your nic to the time an order leaves your nic).
We knew then that we were too slow for large swaths of the HFT space & wouldn’t even attempt those trades.
I haven’t kept up with the industry but I’d guess tick to trade times at the speed edge are in the low hundreds of nanos now. In an environment like that a 1ms time improvement is out of the capabilities of your software/hardware engineers and can only happen at the network.
