Thank you for the feedback. We have web parts that affect the speed of the page. I am aware of the performance hit that the client-side web part model presents. It makes zero sense to move the procedural code of constructing a web page into the browser. Moving traditional server side operations into the browser, along with all queries and data manipulation that go along with that is a major contributor to the slow response times and the poor feedback that we get from our SharePoint users. We have to live with that.
What I struggle to contend with are the myriad of services that offer no discernible value to the end user, and was hoping that there was a way to disable these features.
In my previous post I shared a list of the offending files directly from the debugging tool in my browser. These are the files you would see in a fiddler dump. I will send that to you.
I'm trying to find out if there is a way to prevent any of these scripts from running.
For example, in the SharePoint on-premise platform, we were able to turn off the WsaUpload.ashx call (the Customer Experience Improvement Program, which uploads our usage data 5 times on each request and adds about 1 second to each page load), but apparently we cannot disable this feature in SharePoint Online.
Thank you for your help!
