#21371 Changed the OpenSsl code to use a "custom" bio that uses the buffers from managed code directly rather than using an interim MemoryBio to stop extra copying.
This alone didn't provide much performance however I have modified the encrypt side to write directly to the output buffer, if the content is too large it will then send that to the socket and return to get more of the frame/frames.
This should setup the future for improvements on the read side and to react to Buffer/Span changes.
The performance diff I see on my hardware using the Techempower plaintext on Ubuntu 14.04 with SSL turned on is as below these are unconfirmed numbers. There is a clear convergence of the new and old code as the send sizes get bigger, the numbers don't include the HTTP Header, so the 11 bytes == Hello World. The tests use 256 connections, and pipelining with a depth of 16

Problem
Enabling System.Net.Security.NegotiateStream for Unix.
Solution
This PR introduces the implementation of NegotiateStream based on native implementations of gssapi
The native implementations used are mit-krb5 on linux and the built-in GSS.Framework for OSX.
Also included are scripts to configure and deploy KDC on the host machine so as to run the associated tests.

Port https://github.com/dotnet/runtime/pull/39199 to release/3.1.
Summary
ManagedWebSocket is the WebSocket implementation returned from WebSocket.CreateFromStream and used by both ClientWebSocket and ASP.NET Core. Sends on a WebSocket can't run concurrently, and there's a lock that protects access to shared resources, including a pooled buffer. The code that ends a send operation returns the buffer to the pool and releases the lock, but it does so in the opposite (wrong) order. As such, a second concurrent send could end up trying to use the buffer concurrently with the first send operation releasing it.
Customer Impact
Initially reported as a sporadic ArgumentException that escapes from within the WebSocket implementation (from valid usage). But in theory it could result in data corruption throughout the process, with a buffer being returned to the pool while it's still in use.
Regression?
No.
Testing
Unit tests.
Risk
Low. The fix just swaps two instructions (in three places) to return the buffer before releasing the lock.

Port of https://github.com/dotnet/runtime/pull/32768 Fixes https://github.com/dotnet/runtime/issues/32767
Description
An Expression lambda delegate cache was added in .NET Core 2.0. If there are many calls to Expression.Lambda<TDelegate>() overloads with distinct delegate types which result in cache misses, the result is a performance regression.
Customer Impact
Performance regression with many calls to Expression.Lambda<TDelegate>() with distinct delegate types. Customer reported this impact in a migration from .NET Framework to .NET Core.
Packaging Impact
None
Regression
Regression from .NET Core 1.0, and .NET Framework.
Testing
See benchmark testing in https://github.com/dotnet/runtime/issues/32767.
Risk
Low. The change avoids the cache and allocates a distinct Expression<TDelegate> each time.
