You'll really just have to test side-by-side see. I've only done anecdotal testing with more moderate-size layers and found file geodatabases to be about twice as slow as a shapefile. Maybe others have done more rigorous benchmarking.
MapServer 7.0 ESRI FileGDB API 1.2 GDAL 1.11.2 Steve From: mapserver-users [mailto:mapserver-users-boun...@lists.osgeo.org] On Behalf Of Mark Volz Sent: Monday, February 01, 2016 2:39 PM To: mapserver-users@lists.osgeo.org Subject: [mapserver-users] File GDB performance vs Shapefile Performance Hello, My interactive mapping application is currently using Shapefiles to store the contour lines. At 1.5 GB the Shapefiles are rather large. Instead I am considering using a File Geodatabase which will only take up about 500 MB. Is there a significant performance loss between Shapefiles and File Geodatabases? And are there any performance tips and tricks for using File Geodatabases? Thanks Sincerely, Mark Volz, GISP Lyon County GIS Coordinator
