Generally, YJIT adds memory over 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. -We use `--yjit-exec-mem-size=64` for Shopify's Rails monolith, which is Ruby 3.3's default, -but smaller values like 32 MiB or 48 MiB might make sense for your application. +`--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. ### Enabling YJIT lazily |
