ArcPro Slowness and the Diagnostic Monitor

CodyPatterson — Wed, 11 Jun 2025 20:23:42 GMT

Hey all,

ArcPro Version 3.4.0

A coworker has reported that their ArcPro has become increasingly slow, after a time becoming so slow that it's around 15 seconds between each operation. It's reported that when the Total CIM Reads - UI hit around 8 million, the software starts the 15 second trend, at around 15 million it's completely unusable. I'm not sure exactly how to interpret this as I'm not sure the interaction of the software and this diagnostic attribute.

Are there any other things I should look for in this? I've rarely used the Diagnostic monitor myself and am curious how we should proceed the troubleshooting. We have followed this guide:

Troubleshooting Performance Issues in ArcGIS Pro (esri.com)

Any help would be appreciated!

Cody

It might help if you share the version being used. There have been multiple bugs in the past affecting various versions.

Hey @Eugene_Adkins

As my coworker mentioned, it is version 3.4.0, I've added it to the post as well!

Hi @CodyPatterson
Have a look under the HTTP tab in the Diag Monitor.

Do you see a bunch of license checks happening?

There will be entries similar to:
<HTTPRequest start="5/11/2024 10:20:05 AM" duration="235" thread="39940" status ="200" url="https://www.arcgis.com/sharing/rest/portals/MYAGOLACC/subscriptionInfo?token=THETOKEN&f=json"</HTTPRequest>

Almost every operation you do will be delayed until the checks are done. It can be anything from a few ms to near a minute on a bad day. Imagine trying to change colours in a geology map... Every single colour change will be delayed!!!

It was ~~fixed~~ enhanced in 3.5 🙂

Have a look at this Idea:
