Hi all, I'm using mapnik in combination with tilecache to render off line a map. My question is about mapnik performance: what seems strange to me is that I have a 100% usage for cpu while the memory allocation is very low (20 - 30 MB). I'm using shapefiles as data source and their total size is about 2 GB (off course not all shapefiles are used for all zoom levels). My computer has 2 GB RAM and I'm using indexes for the shapefiles.
My idea is that mapnik can't load into memory the data files and that it's reading from the hard disk: it would explain the high cpu usage and the not so good performance. Any suggestion? Thank you in advance Marco
