Comment:
Okay, the [https://github.com/pion/dtls/pull/200/ fix for this] was merged
at
[https://github.com/pion/dtls/commit/147774b64b6a8ac9bd0af5a7efff69ee8e0fd4a8
8e0fd4a8] thanks to Sean.
Note that this will also improve performance at the client side. Still not
sure if this is the cause of the issue that dcf was seeing originally, but
it's reasonable that a proxy-go instance with more than 2 or 3
simultaneous clients would show 100+% CPU usage earlier. We can deploy the
changes and see what we get.
I'm putting this in needs_review to review the patch that removes logging:
