Hi guys

Would like to hear from your experience(s) on using Erlang with TLS/SSL.
The default Erlang stack doesn't perform well, Google says.

Does anyone use Erlang in production behind:

. Hitch: https://hitch-tls.org/
. Envoy: https://www.envoyproxy.io/
. HAProxy: http://www.haproxy.org/
. ???

Or directly using:
. gen_ssl: how to make it scale?
. fast_tls: https://github.com/processone/fast_tls
. ???

Some of the solutions above are fast, some scale well ... but all with
downsides (ex. Hitch adds  200kiB overhead per connection).

We’re planning to go live with a fairly large number of secure connections:
45k - 75k. The sessions should be short (few seconds). Transferred data
should range between 50KiB to 1miB max.

Insights and/or feedbacks are very welcome.

/Frank
