Just how scalable is Grails?

Question

I\'m looking to make a website that will probably get some heavy, repetitive traffic. Is grails up to the task?

Answer 1

The scalability of your web application won't really depend on what language/framework you choose to use, but rather how your application is built. You can build a scalable web application in Grails, just as you can build an incredibly slow application in C++. If Grails is the framework you would like to use, then use it; you can always rewrite the slow parts in Java or another fast language, if need be. (After all, that's what Twitter did with Scala.)

Disclaimer: I've never actually used Grails.
