defrecord inside defmacro

Hi all, I started learning Clojure very recently by rewriting my old college Java project to Clojure. Having bunch of records I wanted to automate record creation with macros and to finally learn Clojure macros, but I got stuck. Example (Real code will be more complicated but I need to make

[Review] Slow server, not maxing out CPU

I'm fooling around with Clojure and I implemented simple server that will randomly query/insert/update/delete random data from DB on every request. When I benchmark (wrk) server is slow (compared to similar solution) and I noticed that CPU is not maxed out, it's about ~30-40%. I used http-kit
