Internet Explorer 11 performance with SPFx
Internet Explorer 11 is still the standard operating environment for many companies which makes the pages with multiple SPFx webparts really slow.
Each SPFx webpart by design adds at least 4 cached...
Have you tried checking whether the browser is caching the files correctly? Is something, e.g. cache control settings, causing it to reload these every time?
Hi Bill,
Thanks for your reply.
Yes, I confirm that caching is done correctly by Internet Explorer by analysing HTTP traffic over Fiddler.
To give a better idea about current setup, we have a SharePoint 2016 environment with home page which contains 9 SPFx webparts.
