[erlang-questions] Sender punishment removed
Fri Jan 19 12:51:33 CET 2018
I asked the same question in Erlang Slack chat and got the answer from
@seriyps we have been wanting to remove it for a very long time, as it was
introduced mainly to solve problems with non-smp systems and doesn't do
much in smp systems. We are just now in progress of re-writing how process
to process signal/message passing works, so we decided that it was time to
remove sender punishment at the same time.
Also, we have lately been writing a lot of more benchmarks in order to
track the performance of various parts of the Erlang/OTP and
senderpunishment makes it very hard to get predictable performance.
So I saw that the sender punishment was removed in . The commit message
