Hi Jelmer, I made a quick test with one shapefile of size 580 MB containing 1.2 million polygons. Shptree (from FW Tools 0.9.8) with default parameters took 2 min 30 secs to run with 3 GHz Pentium and Windows XP and memory usage grew not more than 200-300 MB during the process. Of my 1 GB I had all the time more than 500 free. The idle usage seems to be around 200 MB. With quite a similar datasets we have rather different experiences but I do not have any idea why. Regards, Jukka Rahkonen

You may have version problem (dll or so). Mine is 218MB (Only has 1132271 records :P). Smaller files DID work. Like I said, it loads all the entries into memory and then crashes when trying to address more than 2GB. -- Jelmer
