@JoshuaBixby , Is there any documentation or warnings from Esri that ArcGIS Server 11.x requires more RAM to run the same number of services as ArcGIS Server 10.x?  This thread is the first time I have come across this information. ... View more

Thanks Joshua.  That is great info for the planning of our 11.5 upgrade. ... View more

@JoshuaBixby wrote: The organization I used to work for initially had instability problems with ArcGIS Enterprise 11.x until we analyzed memory utilization of the ArcGIS Enterprise processes and subprocesses.  It turns out the ArcGIS Pro runtime used in ArcGIS Enterprise 11.x results in ArcSOC.exe processes having about 50% increase in total memory footprint.  I say total memory footprint because it wasn't more RAM being used but more virtual address space by the processes.  It turns out we were hitting or nearly hitting the committed memory limit of the server, and the entire ArcGIS Enterprise framework would become unstable at that point.  Once it became unstable, the only option to stabilize it was to stop the ArcGIS Server Windows service and restart it. I suggest you monitor the Committed memory usage of the server, and not just RAM.  If you are getting over 90% committed memory for any period of time, I would update the virtual memory (page file) settings on the server.  Just the other day I had one of our server admins tell me: "With the latest versions of Windows Server we prefer to let the OS manage the size of the page file".  That was a general comment on Windows Server 2022 - not specific to ArcGIS Enterprise.  I had asked the server admin to collect information on the paging file size from our 3 existing VMs running ArcGIS Server on older Windows Server 2016 VMs. @JoshuaBixby is your recommendation to increase the page file size?   Bernie. ...

We had a similar problem with an upgrade.  We went from two ArcGIS servers running 10.2.2 to three ArcGIS Servers running 10.7.1 on new VMs.  It was great to have the new system on new VMs so we could do comparisons between the old and new system.  You have to figure out where the bottleneck is that is slower in the new system compared to the old system.  You can't just throw up your hands and complain that it is slower.  It took us a lot of time and benchmarking but we figured out it was our file server.  The location for the config-store required OpLocks to be OFF.  The location for our FGDB required OpLocks to be ON. The problem is likely different in your situation so you are going have to dig in and find the bottleneck.  We were lucky - we had a networking genius on our IT team to help with the diagnosis.  But it still took time.

Can you filter on another attribute?  Are the polygons assigned a sequential objectID?  Could you filter for the largest (e.g. newest) objectID?   Here is a similar example from my own work: I have a Notebook that writes records to an AGOL hosted table.  I truncate the data to the 2000 most recent records.  This means the oldest record has objectID = 1 and the newest record has objectID = 2000.  I use these objectID values to filter data in an ArcGIS Dashboard.   Bernie. ...

Thanks for the response @CodyPatterson.  I am aware of the Health Check URL.  I was more interested in some guidance on how to implement this on a Windows VM so the script would trigger following a reboot.  What language to use?  How to force a reboot in a script? etc.  I would imagine it should be tricky to force a reboot.

Amanda,         That is a great explanation of Esri vector tiles.  But wouldn't it be better if customers had a choice?  You can have "basic" vector tiles without Portal/AGOL.  Or, you can combine vectore tiles with Portal/AGOL and you can also have restyling and .... etc. Bernie.   ... View more

Add a filter to the dashboard for the regions. The user can set the filter so they only see the relavent data. https://doc.arcgis.com/en/dashboards/latest/get-started/filter-data.htm  Or, create one dashboard for each user and apply a different filter in each dashboard. Bernie. ... View more

If you know why they are asking for the same feature class in two map services with different coordinate systems you can help the client understand why it is / is not necessary.  Perhaps they want a geographic coordinate system for a globe view and a projected coordinate system for a 2D view?? ...

Why do you publish it in two coordinate systems?  Is it to ensure accurate measurements?  Is it to allow for faster draw times? Here are some thoughts to consider: When you add a map service to an AGOL web map, the map service is reprojected on the fly to the basemap's coordinate system. The ExB Measurement widget uses the ellipsoid-based geodesic calculation to calculate measurements. https://doc.arcgis.com/en/experience-builder/latest/configure-widgets/measurement-widget.htm  We only publish in one coordinate system, and it is not Web Mercator.  We publish in EPSG 2953, https://geonb.snb.ca/arcgis/rest/services  Bernie. ...

@IakovosFlorides, Based on your description it is unclear to me if the slowness is caused by the database or by your services.  You did not mention the CPU and RAM utilization for your ArcGIS Server.  Is there much free RAM and CPU during peak activity?  I like @MichaelVolz suggestion.  If your users do not need to immediately see the latest changes to the Enterprise geodatabase you can update the feature classess to one or more FGDBs.  Then use the FGDBs as the source for your map services / feature services.  Create automated scripts that run during slack times to move data from the enterprise geodatabase to the FGDB I get the impression that you have multiple feature classes in your map service / feature service.  Are you using dedicated services or a shared pool service?  I would recommend publishing the feature classes with the heaviest traffic as their own dedicated service, e.g. one feature class = one service.  If you only have a few feature classes you can publish them all this way and assign more instances to the services with higher traffic.  If you have a lot of services you can publish some of the lower traffic services in a shared pool.

We just completed some special tuning for an event that we knew was going to greatly increase our traffic on one specific map service.  We used some rules in Apache to identify incoming traffic for this map service and then split the load 50 / 50 across our 3 PROD servers and 3 TEST servers.  Our TEST servers have the same specs as our PROD servers but TEST gets much less traffic.  It worked perfectly and we experienced no problems with the additional traffic.  We'll undo the special Apache config in a day or two.
