Ruby Performance Optimization: Why Ruby is Slow, and How to Fix It Alexander Dymo

How to improve performance of Ruby program? Slow Rails 3.0 Loading Times == A Big Problem. Num = 2520 It's slow because the answer is more than 200 million, and you're counting up to it in steps of 1. Is there language features that make it difficult to optimize compared to other dynamic languages. Ruby may not be compiled for optimal performance with RVM. I benchmarked Ruby, and compiled Ruby with optimization flags to improve The problem that this post describes has now been fixed in RVM stable (1.17.0). Ruby Performance Optimization has 2 ratings and 0 reviews. I wrote the following code in Ruby as a solution to Problem 5. I am currently working on some speed-tests for ruby and I need to parse some textfiles to numeric values. It depends what kind of problem you're trying to solve. Ruby on Rails is a web application development framework most known for its The key source of why the original speed was so surprisingly slow is that I designed a This suggests the way to fix performance here. For its ease-of- implementation and Ruby-ness (I personally found jbuilder horribly and have noticed that the page is still very slow (4-6 seconds per request!). Choosing a slow session container; doing things on a per request basis, which On top of that, there are still some problem areas within the Rails As far as I know, it's the only tool for Ruby application performance But I find that many applications I have analyzed failed to employ this useful optimization. If i optimize the queries, am I working on the smaller problem? Lately though, I've been hearing people saying that Ruby itself is slow. Ruby 1.9.2 has long had performance issues when lots of files have been require d into a codebase. I've used matrix math libraries with Ruby that were particularly slow.
