So we have a PLSS(sections & ranges) layer for the entire US. It's roughly around 2 million features. Every time we bring in this layer it slows down the entire MXD and lags a lot. I know it's this layer because when I turn it off the mxd performs a lot faster. I did some research and I found a few tricks but none work:
What else is there to do, besides breaking it up?
I sometimes use the map service below, which is ALOT quicker.
How do I get my layer to run as fast as the map server. I can see that its a png file that uses in ArcGIS Online.
Does this mean the data is in a raster format?
I tired Polygon to Raster but then it cant use labels and the symbology doesn't work well.
What am I missing here?
Since you haven't said what exactly your research entails, I will ask, you have read over all three sections of An overview of designing maps for optimal performance—Help | ArcGIS Desktop ?
As Esri's documentation mentions, there are numerous factors that influence a layer's performance ranging from data structure to symbology to labeling and more. You will need to provide more specifics to get more specific feedback.
I read over a bit of the material gave me it helped. It improved the speed a bit.
However, I still want it as fast as that service that i mentioned.
I should have asked how do I make a mapserver like above? How is that one so fast and responsive?
Sorry it might be a generally question, hopefully you can help me out.
Given the scale/scope, density, and complexity of the CadNSDI data sets, I am guessing a non-trivial amount of time went into optimizing the data and layers to make a high-performing map service.
Not to sound like a broken record, but it is hard to offer specific suggestions when you have shared so little about how your data and layers are structured.
Thanks for the advice Josh.
I got things to work a lot faster by:
- putting the data in a sde rather than a fgdb
- making the labels from a single field instead of multiple fields.
- added it to a basemap layer
- Removing halos and using shadows
- Having it in the same CS.
All these changes made it lightning fast! I got it to load from 30 seconds to almost instant!
Thanks Josh for the article.
I am glad you got it working better. I am a systems engineer responsible for deploying ArcGIS Enterprise, and I commonly deal with this issue, not directly but from people who complain that ArcGIS Server is slow when in fact they have created a slow service.
