Thanks @easco. This is helpful.
I’m not sure if a Mint-like app is considered math intensive or not; but with multiple simultaneous users each viewing scenarios based on on their unique data sets, it’s possible that the app may benefit from Erlang’s multi-threaded/parallel processing capabilities.
I think the math can be characterized as mostly arithmetic and time value of money operations applied to tables/arrays of data up to 1000x1000.
I suspect there is a threshold of math/computation-intensivity where Erlang is not well suited. I’m trying to get a working sense of that threshold, and an appreciation of the classes of apps that fall beyond that threshold.
Thanks again for your comments!
