Re:I left Heroku for OpsWorks and shaved 40% off response times by banachtarski on Friday February 07, 2014 @11:40PM (#7200293)
What do Opswork, Chef, and the Heroku platform have to do with response time?

Did the author investigate why the response time were that slow to begin with?

I wouldn't say they were "slow to begin with" but improved speed is always nice. I think the major contributing factor was access to newer, more powerful instances. Heroku Dynos run on very old EC2 instances.
