Thanks for your response, Rebecca. I will give some thought to FGDB vs SDE. Intriguing... I do own the imagery extension already and use it regularly to publish. We always cache directly from the mosaic dataset.

Neil Thank you for responding. I have to imagine they are doing this due to the size of the images (3" GSD). I'm not an expert in image processing on-board the aircraft, so I'm starting with what comes off the plane. Did you have any advice on jpeg vs geotiff?

Dan Thanks for the response. I'm very familiar with mosaic datasets and overviews - been using them for many years. My question is really about whether it makes sense to have the vendor convert these jpeg (80) images to geotiff or not. I'm looking for anyone who's built their datasets using jpeg images vs using geotiffs.

We need to decide on a deliverable format for orthophoto images to be captured during an upcoming flight. I have always used geotiff or tiff. Our vendor tells us the images come off the plane in jpeg (80 compression ratio). We could have these converted to geotiff without any further compression. We could also choose to have them delivered as that raw jpeg with world files. Or we could go to jpeg 2000 to avoid world files. In this case, the jpeg's will be about 1/10 the size of the geotiff. We plan to reference all of these images in a mosaic dataset. Mosaic dataset image loading time is not a deciding factor for us because it is only a one or two-time thing. Rendering performance is though. We will cache the images for the web and caching time is also not important to us because we only cache it once or twice. Bottom line - how well these images display in ArcGIS Desktop/ArcGIS Pro from a local SDE geodatabase mosaic dataset is the most important variable for me. Storage space is the next most important factor. Which format would you choose and why? Thanks in advance for your feedback.

Thanks, Vince. Haven't used SDE app server in many years. I am looking for just what you describe - database tools that help me analyze specifically how SQL is using memory. Bottom line is do I need 8 or 16 Gb on my new database server?

Thanks, Chris. I'm trying out the SolarWinds DPA trial. Looks useful. I also stumbled across the DBCC MEMORYSTATUS command for SQL. Also provides some good info.

Thanks, Jake. I tried using the System Monitor tool a couple of years ago. I found it difficult to use and seemed to focus more on ArcGIS Server performance than on database performance. Have their been improvements in the last year or so?

Thanks, Chad. I'm actually referring to memory usage on the database server - not the ArcGIS Server.

Can anyone suggest some sql queries/scripts that could help me monitor SQL Server's system memory usage on an active enterprise geodatabase instance? This SQL instance is primarily supporting ArcGIS Server REST services. There are very few Desktop connections. I'm hoping to really examine my memory usage so I can right-size my database server going forward. Thanks

Thanks, Lindsay. We've actually moved this function to some different software.

We have staff who edit our sewer manhole points daily. Every month or two, the feature extent on this layer gets way out of whack. We haven't been able to pinpoint any specific editing process that we think would cause this. I typically just recalculate the feature extent and move on, but we'd like to find a permanent solution to this issue. Has anyone else experienced something similar? Our point feature class is stored in a feature dataset using our local state plane coordinate system. The data is always edited in a map document using the same coordinate system.
