“It’s also worth mentioning that there shouldn’t
be doubt in anybody’s mind at this point that
Ruby itself is slow. It’s great that people are
hard at work on faster implementations of the
language, but right now, it’s tough.”
Alex Payne, Twitter
Does this discourage me from Ruby or Rails? Hell
no. To me the elegance of the language
completely dominates its ﬂaws... I’ll wait for the
performance and scale issues to be ﬁxed in
You will also ﬁnd that Ruby is one of the slowest
languages in existence.
quot;Ruby is slowquot;: a JIT is under development, the
VM has a lot of room for performance
improvements, and hardware keeps getting
faster. Java was slow for the hadware that
existed when it was originally created.
I for one am scared of Ruby because ... it's
known to be slow, so if you become The Next
MySpace, you'll be buying 5 times as many
boxes as the .NET guy down the hall.
Rails is for the vast majority of web applications
Fast Enough... I just happen to care much more
about free developer cycles and am willing to
trade the former for the latter.
David Heinemeier Hansson
Would you rather come to market late on the
back of an inferior development environment
(asp.net) or make it to market ﬁrst with a
superior development system and work to
alleviate the scalability issues?
