Benchmarking Ktor and http4k
This week we return to comparing the http4k (https://http4k.org) and ktor (https://ktor.io/) http libraries, specifically looking at throughput in requests per second.
I’d like to be able to stay “stay tuned to see which is faster”; but the truth is that, on my laptop at least, both seem to be able to route and process requests faster than the operating system is able to accept them.
So instead, stay tuned to see some interesting benchmarking code that should come in handy next week.
