SPIisLatency and SPRequestDuration Response Headers in SPO Pages
(11/5/2017): For anyone interested in the outcome of this issue: Bill and I were at the DEVIntersections conference in Las Vegas this past week. A bunch of us went out for dinner one night, and I took the opportunity to approach him on this topic. That seemed to jump-start things, and he's followed-up with an internal (to Microsoft) email to the developers to get an appropriate response.
When I have some sort of semi-official reply, I'll update this thread. Stay tuned!
Have you received any feedback yet on this issue?
Nothing definitive, no. Bill Baer approached the dev team about it, and they seemed to indicate (or think) that it had something to do with web parts on a page. I called BS on that, because it's happening on blank pages. Bill also didn't seem to buy it, but he said the dev team would need a repro case to make headway. I generated the necessary data to repro the case, and that's where it was left.
I'm planning to send him another note today to see if there's been any progress.
Any updates on this yet?
Joakim,
I can understand if you (and others) had thought that this issue/question had died. It didn't. I've made myself a royal pain-in-the-butt for Bill and a couple of others, and I think we're starting to make progress. My hope is to have some meaningful discussion with some folks internal to Microsoft soon.
As if to underscore the issue, one of the sessions I'll be presenting at the upcoming SharePoint Conference North America (in Vegas) is on performance ... so that places some extra priority on getting answers soon. It's obviously difficult to talk about performance and measuring it when two of the HTTP headers that matter the most for that are in Limbo!
Stay tuned.
