What is AdequateRecord Pro™?
AdequateRecord Pro™ is a fork of ActiveRecord with some
performance enhancements. In this post, I want to talk about
how we achieved high performance in this branch. I hope you
find these speed improvements to be “adequate”.
Group discounts for AdequateRecord Pro™ are available
depending on the number of seats you wish to purchase.
