That's correct for throughput but not for latency. Tile processing will add to total time needed to get tile because reading and processing can't run in parallel. I'm sure cgi will provide tile faster (though it might be insignificant compared to total time) _______________________________________________ Tilesathome mailing list [email protected] http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/tilesathome
