There was a time when I used to advocate my fellow folks here at HN (and possibly even reddit) to go for a framework built on faster languages like GoLang or Scala or even using platforms like Node.js and avoid slower ones like Rails. Now, it's time for me to apologize to the community for giving you wrong advice [1]. Turns out I could never have been more wrong. I wish I could write a long post describing each of the WHY's, but I'll be more succinct, this time: 1)If you can throw money at something at something and scale, then you're as good as gold. Rails allows you to do this. Oh, and supportive statements from Pinterest guys on the same topic - [2]. 2) The speed of a language has nothing to do with the success of your business. NOTHING. You can go with the world's slowest language and still be successful. Best example of this is Basecamp itself. As a matter of fact, even many of the popular sites (heck, even popular porn sites) still run on PHP (PHP was one of the slowest from the frameworks speed comparison conducted by Techempower - [3]). 3) The actual thing you want to be able to do is quickly iterate on your product and constantly have it evolve. This is only possible if you have a complete framework that doesn't force you to re-invent the wheel. For example, when I wrote a framework by myself in GoLang, Scala, I found myself focusing too much on basic stuff like authentication, instead of focusing on the features that are needed for the actual product. 4) (P.S this is my personal opinion) I've tried all major frameworks out there and I've come back to Rails again. Why? Because its philosophy resonates with me (yes, now it does). For me, the three most important elements for a successful product are - Speed, Reliability, Consistency. Rails provides me with all these three. (And please try Puma, it's pretty impressive!). As for me, the ability to seamlessly integrate SASS, Compass and HAML (which help me divide my product development time multiple folds) makes Rails a clear winner for me. And now Active Job, Deliver Later, Adequate Record, Web Console now make Rails much more complete than ever. (Thank you DHH!) In the last 6 months, I've written 4 complete products for 4 different people (one of them, being mine) that is well tested and works perfectly as intended. Compare this to something like last year where I spent 2-3 months writing just a single software product (for myself) while I was trying to use GoLang (<- or insert another faster language here) (because I also had to take care of all the other things like Authentication, etc). The point is, ultimately you want to run a successful business. And if you're worried if the slowness of your language will hinder it's growth, then nope. That will not happen. I hope this helps someone. Cheers.
