Don't say I didn't say I told you so
I’ve had, shall we say, heated debates with a few of my friends about the stability of Ruby on Rails. After hearing about the way Ruby on Rails handles database interactions I was fairly convinced that it would make serious scaling a huge pain in the butt. Today, by way of an interview of a Twitter developer, comes the answer I’ve been expecting:
Running on Rails has forced us to deal with scaling issues – issues that any growing site eventually contends with – far sooner than I think we would on another framework.
…
All the convenience methods and syntactical sugar that makes Rails such a pleasure for coders ends up being absolutely punishing, performance-wise. Once you hit a certain threshold of traffic, either you need to strip out all the costly neat stuff that Rails does for you (RJS, ActiveRecord, ActiveSupport, etc.) or move the slow parts of your application out of Rails, or both.
…
It’s also worth mentioning that there shouldn’t be doubt in anybody’s mind at this point that Ruby itself is slow.
I knew ActiveRecord was a pile of crap from the minute I read in their documentation that it was “only” 50% slower than going straight to bare metal. Combine that with the fact that you can’t connect to more than one database server, force indexes or do other various MySQL-specific DB foo and you’ve got a recipe for disaster once you hit a certain amount of traffic.
All your life are belong to the Intarweb
I’ve been thinking about the Internet and, especially, craigslist lately. Since moving out to Seattle I’ve relied heavily on both to form new friendships and find new things to do. This is a brief list of how the internet has affected my life recently.
- The whole reason I moved to Seattle was because I met Brad, the proprietor of eNotes.com, LLC found me via an article I wrote.
- My closest friends in Seattle are Garren, John and Andrew were all met in one way or another through craigslist.
- I’ve disc golfed, snowboarded, ran, walked, talked and drank with numerous people I’ve met from craigslist.
- I’ve gone on a few dates from craigslist. I won’t bore you with the details, but let’s just say dating in Seattle sucks.
- I’m going to Sasquatch with a girl who just moved here from Florida and was looking for a ride.
It’s really staggering now that I think about it. There isn’t a single person that I can think of that I interact with daily here in Seattle that I didn’t meet online somehow.
