Improving 500px API Performance: Presenter Model Caching
Madigan Kim

Great article Madigan!

I was the geek at the Rails Talks who forwarded over the performance issues in ActiveSupport, so I’m super invested in finding the issue at the heart of the performance drop (and I love 500px!)!

Did you ever find out what was responsible? I mean, the presenter models weren’t causing major performance issues in Rails 3, what changed that caused the performance drop in Rails 4?

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
