I’m curious, who is even the target customer here? Places like FB and Google are working on the problems themselves. They talked about some “latency sensei” product or something but what is it gonna tell me? How many nanoseconds it took for my API request to go from a load balancer to the web server, with 5 ns precision? Is that precision really needed?
