Using Puma and JRuby without threadsafe Rails application

Question

I've built my application using MRI without taking into consideration threads or concurrency, and so the application is most definitely not threadsafe (many of dependencies certainly not). My question is could I still port this to JRuby and use Puma without using config.threadsafe! and still see improvements?

是的，您可以“将JRuby运行时本身视为线程安全的。从Java中，您可以跨线程安全地使用单个运行时，前提是这些线程中的代码不会造成线程不安全。线程安全并不意味着您的代码将始终正确运行；您仍然经常需要确保线程不会踩到彼此的修改。”
