The product name “RPM” stands for “Rails Performance Management” – which is an anachronism, now that we support Ruby, Java, PHP and .NET (stay tuned for other languages).
The suffix “rpm” stands for “Requests per Minute”. Typically used to measure throughput, either for the whole application, or a specific Web Transaction (Controller Action in Rails).
