[I Gusti Ngurah Oka Prinarjaya]

Hi,

Referrring to @Max Lapshin <max.lapshin@REDACTED> report, why it's always
problem in SSL? I mean not-smooth.

But, I do really appreciate and thank you super much for all of the hard
and awesome work for the Erlang/OTP Team!

I wondering lots of improvements in scheduler system, more faster and
smarter scheduler system.
