Understanding the Diagnostic Monitor and performance issues
Hello, I am looking for some help on how to interpret the Log in the Diagnostic Monitor. I frequently experience lags and slow performance, so I had a look at the Diagnostic Monitor, but I don't understand what it is telling me.
What I see a lot is "CSharedQueue Stall timeout", often several in a row (up to 40 or 50!), which can take up to a minute, combined. Any clues what this is?
Another thing I noticed is, that AGP often seems to be accessing data that are not in any open map. I have observed this in several projects, actually.
The problem with this is, that some data are on network drives that are painstakingly slow, especially when accessed through our VPN when working from home. E. g. in the screenshot above it is an elevation raster on the X drive. I know that network drives and AGP don't go together well, but that is how my organisation provides our base layers. I have my own data and projects saved locally and avoid tasks that need layers from the network drive when working from home. This approach worked well in the past.
But it seems to go beyond unnecessary data access: Today I was amazed to see the log fill up with entries related to layer drawing, symbol drawing and label drawing. No map was open! Why did AGP draw one – or maybe even several? If I filter for any specific layer I get 10 instances each of Beginning of layer draw and End of layer draw. Did AGP just draw every layer in every map in the project, even though they where closed?
What I actually tried to do was create a new (empty) map. I had closed the one that was still open, so that only a catalog view remained, and then used the right-click-menu in the catalog pane to create the new map. It took AGP 5 minutes to get it done! But only the last few entries in the log seem to be related to this.
Am I completely misunderstanding the log? Is there any documentation for the Diagnostic Monitor (I searched, but couldn't find anything). Any help is appreciated!
Currently using version 3.5.2 with a concurrent use license
(but I checked the http tab and all entries seemed to be related to getting a basemap (which I did not need, as no map was open), and not to the licence manager).
