You can find them listed as "whitepapers" at the bottom of ColdFusion.com (as I view it today, at least), so keep an eye there to see if perhaps any others may ever be added.
Here are the docs, with some observations also about their size and version, if available:
- Lockdown Guide (85 pages, currently version 1.0, released Feb 2) - An update to the classic document that Pete Freitag has been doing for CF for a few releases. Everyone should read this, and heed its recommendations. I'll have more to say on that in another post.
- Migration Guide (22 pages, currently version 2.0, no date offered) - Focuses on a few things: how installation on a current server running CF already offers to migrate admin settings; how one can do that with the CF Archive (FAR) feature (available for CF Standard since CF11); using the Code Analyzer, and how to troubleshoot some server-level migration issues. For more on "what's new" in 2016, see the docs page on What's New in CF2016. For more on what's deprecated, see the docs or my other post discussing what's deprecated in 2016
- Server Performance White Paper (9 pages, version 2.0, no version or date info offered) - Discusses specific performance improvements in CF 2016 (not performance of CF in general, nor performance-related changes in previous releases, nor all available optimizations in code or config). It's focused solely on changes in CF 2016 (or could be a huge document), whether regarding existing code/configuration as migrated or as impacted via new config/coding options available. Includes an appendix indicating the server and CF admin configuration for the testing they did.
- API Manager Performance White Paper (18 pages, no version or date info offered) - Discusses load testing done against the new API Manager, and the rate of traffic sustained (very important as an aspect of the API Manager is to act as a gateway for performing, managing, monitoring, caching, and even throttling API calls, whether against CF or any server in your infrastructure). Since the API Manager is a new product, it's a larger document than that on CF, focused as it is only on changes in 2016 (in case anyone may comment that the CF Performance guide is only half its size)
Hope that's helpful. Check 'em out.
