 3-4x of `--yjit-exec-mem-size` in production as of Ruby 3.3. You should multiply that by the number
 of worker processes to estimate the worst case memory overhead.

+`--yjit-exec-mem-size=48` is the default since Ruby 3.3.1,
+but smaller values like 32 MiB might make sense for your application.
 While doing so, you may want to monitor `RubyVM::YJIT.runtime_stats[:ratio_in_yjit]` as explained above.
