[mapserver-users] File GDB performance vs Shapefile Performance

[Lime, Steve D (MNIT)]

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

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,
