Reminds me of how they slow down NYSE tickers, they roll a spool of fiber optic cable instead of having a timer in software.

- kasey_junk 5y agoYou are thinking of IEX not NYSE. And that is a marketing gimmick.
- rootsudo 5y agoAh, yes IEX and, darn it's just marketing?
- kasey_junk 5y agoWell they may actually send traffic down it, but it’s certainly not the best way to solve the problem of slowing down network traffic.
- nijave 5y agoIt seems like one of the easiest to explain to non technical end users. "Yeah, you see we've measured the amount of time it takes a piece of information to move over the longest wire. Then we've calculated the length of your wire and determined the difference. We added that to this piece of code written in (proceed to lose most non technical users)..." Vs "yeah everyone's wire is the same length" Which is fairly easily provable
- kasey_junk 5y agoEvery exchange that I know of that provides collocation has contracted standard length cable routes as part of the offering. So that’s not the gimmick. The gimmick that IEX brought to the table is that they are delaying orders a fixed amount. They own the matching engine so can trivially add that fixed amount in code. But that’s not nearly as fun to show off as a big box of spooled fiber.
- shapefrog 5y agoI am sure there are still plenty of lawyers lined up with tape measures to check that the opposition doens't have a smaller one than them.
- elgaard 5y agoI might be the best way to ensure a minimum latency and convince your customers that you have done that.
