Is there any updated version of this function that also deals with categorical explanatory variables? @DavidArenburg

comment Rails app is really slow in Heroku
I migrated the db to the same region of Heroku and the request times are now actually smaller than running locally. Many thanks!!

comment Rails app is really slow in Heroku
It's 150ms on average. Way higher than your app. I'm creating a Read replica to us-east-1 and I'll check the improvements. If it decreases the latency that much, I'll migrate the db to that region. Many thanks @spickermann!!

@spickermann wow! I had no idea that db latency could be that large. I believe the NewRelic chart I added just reinforce this believe, right?

The database is hosted by Amazon RDS, but in São Paulo region, not in US. In this example there are 18 requests. I'm not sure how to measure the latency between Heroku and db. How can I do that? Thanks!
