...this is all ancient history now though. Come on, 2 seconds on google will find all the arguments and counter arguments about this stuff.
I have yet to read a major "moving on from Ruby" story where it was clear that the use of Ruby and/or Rails was a mistake from the beginning. An architecture that works for 1000 users/day will need to be revised for 100,000 users/day, but that doesn't mean that it would have been a good idea to use the 100k architecture for the 1k product.
Ruby itself has made major jumps forward in performance since then. Much of Ruby's reputation for slowness was earned on an interpreter that no longer exists. It's still not the fastest dog on the track, but it is a ton better than those earlier days.
>>In several interviews, the Twitter developers have pointed out that Ruby on Rails was not responsible for their scaling problems. On the contrary, only the maintainability of Ruby made it possible to do such large-scale architectural changes to fix their scaling problems.
Then again, that seems to have been written in 2010. I'm sure things changed since then.
