imtest133 Posted February 19, 2017 Report Share Posted February 19, 2017 Dear all I want to extract a raster values to a very heavy point shapefile (with 1.700.000 points!) in ArcMap. It takes very long but only uses 37% of my memory? How can I allow ArcMap to use more memory to save my time? http://s4.picofile.com/file/8286974650/photo_2017_02_19_20_36_46.jpg Quote Link to comment Share on other sites More sharing options...
Capricorn Posted February 19, 2017 Report Share Posted February 19, 2017 I don't think this operation uses memory but a processor speed. When you start loading this shape, then your PC uses memory. Quote Link to comment Share on other sites More sharing options...
Lurker Posted February 20, 2017 Report Share Posted February 20, 2017 Capricorn is correct memory only for temporary storage, all the heavy burden goes to CPU anyone can confirm that ArcGIS using the advantages of GPU proc? modern Software should use CUDA or similar function Quote Link to comment Share on other sites More sharing options...
imtest133 Posted February 20, 2017 Author Report Share Posted February 20, 2017 also CPU usage is 31% only Quote Link to comment Share on other sites More sharing options...
Lurker Posted February 20, 2017 Report Share Posted February 20, 2017 see this, and you will understand how ESRI really bad in this implementation https://geonet.esri.com/thread/25105 Quote Link to comment Share on other sites More sharing options...

I had such experience while rendering in 3ds Max. These are the moments when I realize that my CPU fan has another gear Quote Link to comment Share on other sites More sharing options...
Lurker Posted February 21, 2017 Report Share Posted February 21, 2017 if you get your CPU almost 100%, then your computer will be freeze this happen when I run PIX4D process drone data and forgot to set multi core setup (usually I release 1 core and the rest of core for processing) Quote Link to comment Share on other sites More sharing options...

rahmansunbeam Posted February 22, 2017 Report Share Posted February 22, 2017 (edited) I am not sure if you are worried that the operation is slow or the CPU usage is low. ArcGIS is a 32-bit single-threaded application. It cannot use more than 4GB RAM and 1-core at a time. You can try 64-bit background geoprocessing to use more RAM. To use more CPU you can try three thing, try the python console. See this link split your data into 4 part and run the same operation in 4 instances of ArcGIS at the same time. This will use 4 core at a time. ArcGIS Desktop doesn't support distribute operation (I think, like 3DS Max), you'll need to do it all by hand, find some other application who can do the same thing with better speed (ie. 64bit QGIS, Anaconda, R).
