We have noticed for many months an afternoon slowdown (~3:00pm on) when working in ArcMap (Pro does not seem to be as affected). Now that we are working from home, the issue seems to plague us somewhat throughout the day. Further, when I rec and post in ArcCatalog, I no longer see the status window, and when I assume the process is finished, I have to close AC with the Task Manager, and then reopen. I can understand home connectivity, routers, bandwidth, etc. causing some of this slowdown, but I would not expect this when connected directly at our office. We have ArcGIS for Server 10.7.1, enterprise geodatabases 10.7.1, and ArcMap at 10.7.1. Pro is at its latest version also.
We are not a large user of the platform, but do have services published to Server for editing in web maps and apps. I noticed in reviewing the Stats in Server that one service (having a couple dozen editable layers) was getting the majority of the requests when the user was doing some editing. I have no frame of reference (is this a lot of requests or unusual?), but I don't think this editing was causing the overall slowdown. In Windows Task Manager on the Server machine, we did notice there were many (130+ as of this morning) arcsoc.exe instances(?) running. All were using no CPU resources, but had consumed 99% of the memory. My colleagues and I are outside of our wheelhouse, so we are asking for input on what could be causing this routine slowdown. Many thanks!
