That is exactly my question as well. Why would I want YJIT if it is only 15% faster than normal Ruby? Given the memory overhead.

The 15% is for the total request time including waiting for blocked IO.

> All that work allowed us to speedup our storefront total web request time by 10% on average, which is including all the time the web server is blocked on IO, for example, waiting for data from the DB, which YJIT obviously can't make any faster.
