The ruby is getting changed and improved a lot with every release. No doubt the existing demerits of rails are soon going to be history.

Currently for my rails applications I am running Ruby1.8… and exploring 1.9 to get ready as we are heading with nice speed in the rails developments. Modrails has already started making waves all around.
Soon I would be publishing a couple of posts on threads, processes and sockets in ruby… here is a bit on how they are going to be different in Ruby1.9.

In Ruby1.9 the threads implementation is going to be really different than what we all know/do in Ruby1.8. The Ruby1.8 uses a single native thread and runs all Ruby threads within that… which certainly protects the Ruby threads to take on much responsibilities and to completely leverage the hardware with multiple processors.

Now, the good news, the Ruby1.9 allocates a separate native thread for every Ruby thread. But at this very moment it is not fully functional… as because of some C libraries, used here, are not thread-safe that it will not allow Ruby1.9 to take control on multiple native threads. Still, great signs of improvements in these directions… It has been mentioned that this restriction will be removed in the upcoming versions of Ruby1.9 and there will be full fledged implementation of multithreading in Ruby with multiple native threads, and the charm of parallel execution… means a lot more scope of improvements for all related libraries, frameworks built on the top of Ruby.
