You can try Passenger and Enterprise Rails combination before multi-threaded Rails. It's interesting that in his announcement dhh actually downplayed the importance of this contribution, saying it is just another item in the enterprise-readiness checklist. I'm pretty sure I read somewhere that a lot of Ruby-related native code, including db drivers, is written in a way that actually blocks the green threads when the native code is waiting on I/O. Can anyone confirm or deny this?
