[erlang-questions] Erlang Cost Model
Wed Sep 16 21:14:18 CEST 2015
Maybe the Erlang community in collaboration with the larger massive
concurrency community should to come up with (or has and I don't know about
them) some standard concurrency benchmarks? Such an effort may be somewhat
(maybe only slightly) analogous to the various transaction processing
benchmarks that the relational database community developed.
Just as a starting point, here is some work specific to Scala in that
