Rails não Escala



FUD: http://www.techcrunch.com/2008/05/22/twitter-at-scale-will-it-work/

To put things into perspective, though,

Friendster was written in Java to start, and switched to PHP. Myspace was written in ColdFusion and transitioned

to ASP.NET.

When people run into problems scaling sites they

often think that the language is the problem, but I think

it’s rarely the case. Blaine Cook

“The New York Times used Ruby on Rails to pull together, analyze and display election results in near real time on one of its busiest Web

traffic days ever. ”

“They serve up 23 million visitors a month. The conversion resulted in 20,000 lines of Ruby code instead of 125,000 lines of Java code, and most importantly

eased the difficulty they had in maintaining it. Once complete, and optimized their site is now faster than before. They also completed the

rewrite in three months with four developers.”
