We have just updated from ArcGIS 10.3 to ArcGIS 10.5.
Suffering from very slow performance in ArcMAP now with certain things. I've completely re-made MXD's from scratch under 10.5 that I had under 10.3 to remove possible changeover issues.
When I simply tick on/off layers it takes a long time (1 minute or more) to update the display or give me control of ArcMap back.
When I save edits - long time to do that (2 minutes or more)
When I change a layer from editable to not editable - long time (1 minute) to do that.
I'd have maybe 10 layers in the MXD with JPEG 2000 aerial photo loaded in - but not displayed.
Arc Catalog displays layers quickly - as you'd expect. Loading one or 2 layers into ArcMAP also seems ok. But more than that *really* seems to slow it down. I never had extremely slow responses like this under 10.3.
We're putting in a support call but just wondering if anyone else has noticed this - and might know what the cause is. Data sits in SQL 2012 with ARCSDE.
