Extremely Slow Spatial Join

[StephenLocke]

I have a shapefile with about 35,000 properties and another with all of the census blocks in Kentucky and Indiana and need to find    the census block each property is located in.  When I start the join process, it locates the census block for the first 7,000 or so very   quickly and then slows to about 30 features per minute.  I am using version 10.1 and don't recall having this problem (not to this extent) when using 10.0.  Any suggestions as to what I could do to fix this or ideas as to what may be the cause?

Hi Stephen,

Late response here, and I don't know if this will help, but you mention you are using shapefiles.  It is good idea to migrate your work to file geodatabase feature classes for this, and future, processing.  I am not sure it will help with this issue but it is very likely to save you a hassle in the future.

Cheers

Hey,

I'm having this same problem, right now. Did you ever figure out how to fix it?

Thanks,
Julian
