idea Improve the performance of model builder feature selection iterator in ArcGIS Pro Ideas https://community.esri.com/t5/arcgis-pro-ideas/improve-the-performance-of-model-builder-feature/idi-p/968532 <HTML><HEAD></HEAD><BODY><P>The Feature Selection Iterator has been a long time coming for model builder and I use it regularly. Whilst it helps simplify models (we don't need to use Python for looping) I have noticed that it's performance can take a hit when there is a large selection.<BR /><BR />I run models that crunch large datasets and I often find that ArcGIS simply runs out of memory. A solution to this is to select a subset of my data and crunch in batches. OK it means I have to keep an eye on everything and restart the processing but it gets the job done. If I pre-select a lot of data I notice the Iterator takes much longer to run it's make featurelayer routine.&nbsp; So as a real work example I have a File Geodatabase point layer with 12,000 points each needs to be processed individually. If I chuck it at my model with no selection it eventually runs out of memory. If I select say 500 points then the iterator's make feature layer step takes about 9 seconds before it moves onto the next model process. If I select say 2000 points (this would not crash ArcGIS) it takes about 45 seconds to make feature layer.</P></BODY></HTML> Mon, 31 Jan 2011 12:18:51 GMT DuncanHornby 2011-01-31T12:18:51Z Improve the performance of model builder feature selection iterator https://community.esri.com/t5/arcgis-pro-ideas/improve-the-performance-of-model-builder-feature/idi-p/968532 <HTML><HEAD></HEAD><BODY><P>The Feature Selection Iterator has been a long time coming for model builder and I use it regularly.

I attempted to replicate the issue described in the second paragraph and was unable to reproduce the behavior. Would it be possible to share more details on this issue or even <A href="mailto:%20chris_fox@esri.com" target="_blank">contact me</A> directly and share your model? <!-- content transformation source ID: 00a30000009b9en --> </BODY></HTML> Fri, 04 Feb 2011 23:53:38 GMT https://community.esri.com/t5/arcgis-pro-ideas/improve-the-performance-of-model-builder-feature/idc-p/968533#M8803 ChrisFox 2011-02-04T23:53:38Z Re: Improve the performance of model builder feature selection iterator https://community.esri.com/t5/arcgis-pro-ideas/improve-the-performance-of-model-builder-feature/idc-p/968534#M8804 <HTML><HEAD></HEAD><BODY>I&nbsp;just hit the same problem processing 300,000 points.
