Basecamp code runs 18 percents faster with YJIT

Basecamp is currently running Ruby 3.3.0-preview3 and Rails Edge (master branch).We configure YJIT in our servers via RUBYOPT=--yjit-disable --yjit-exec-mem-size=192 and then enable YJIT at runtime via RubyVM::YJIT.enable. This allows us to achieve a faster boot time, compared to enabling YJIT at boot. We also enabled yjit stats to a few servers.We track our metrics in Prometheus, using Yabeda to instrument, and Grafana to render them.
