Peningkatan Kinerja Server Aplikasi Web GIS Berbasis PostgreSQL dan MapServer

Abstract

The PHP MapScript-based web GIS application with a huge amount of geographic data is very slow to load. In this paper, we will scale-up the server to bring the real potential out of the hardware. We will also use caching technique to speed-up both the PHP scripts and the map generation, using APC (Alternative PHP Cache) and TileCache respectively. APC can be used as opcode cache and data cache to speed-up PHP-based web application in general. TileCache solution offers faster map generation and lower resource consumption.
