<p style="margin: 10px 0 0 0">Still random walking through the space trying to get a big picture. Aggravatingly all the MS pages have had the native code removed (e.g. <a href="https://msdn.microsoft.com/en-us/library/ms690697(v=vs.90).aspx" class="external-link" rel="nofollow" style="color: #3b73af; text-decoration: none">here</a></p>
<p style="margin: 10px 0 0 0">On the CLR/Native front, I'm not deciding until I have a better grasp of the big picture. Shimming to C#/CLR is tempting if it can be made to work (probably leave most of the shib stuff native and shim out at an appropriate point) but may just be impossible, pus note <a href="http://www.codemag.com/article/050143" class="external-link" rel="nofollow" style="color: #3b73af; text-decoration: none">this</a> from 7 years ago:</p>
<p style="margin: 10px 0 0 0">TLDR: Using manage code was known to hit performance on IIS7 if noone else was using the CLR</p>
<p style="margin: 10px 0 0 0"><cite style="font-style: italic">It’s also important to understand the potential for doing the wrong thing with all of this power. First keep in mind that managed code is slower than native code in the Web server. By introducing managed code into the core server you are slowing down the performance of the Web server. Specifically, the context switches between managed and unmanged code are expensive when running in Integrated Mode and with managed modules present. I’ve talked to some of the Microsoft developers, and they are taking a hard look at optimizing these context switches by trying to batch calls to managed code components as much as possible, staying in managed code as long as possible.</cite></p>
<p style="margin: 10px 0 0 0"><cite style="font-style: italic">Managed code is optional by default-all the core modules are native code, so adding managed modules is an explicit decision you have to make. If you’re already using ASP.NET then this decision is probably a no-brainer. But if you’re running raw ISAPI extensions or modules today, you’ll probably have to take a long hard look to see whether managed code is going to be a good fit in terms of performance.</cite></p>
<p style="margin: 10px 0 0 0">In practice - in 2018, how many people will not have at least one CLR application in their IIS server?</p>
