I try to use spatial autocorrelation and hot spot analysis to find the clusters on the change in appraised values of single family housing from 2004 to 2008 in Dallas County but failed.  The process bar stuck at 0% and never goes up in 5 hours. The sample size is around 500,000. But if I try commerical and industrial parcel, it works. It needs 40 mins to run 27,000 parcels and get the results. I am wondering is there an upper limit for spatial autocorrelation/hot spot anlaysis? Which means if there are too many sample size it cannot work? Or I set some config wrong or need change some setting? If anyone know the solution please help me, thanks a million.
