Peningkatan Kinerja Server Aplikasi Web GIS Menggunakan TileCache

Abstract

Nowadays, everybody knows Google Maps. Map on Google Maps is shaped from small image called tiles. Loading a world map on all zoom levels need a lot of amount of time. It is better just to draw tiles that needed only by the map and save that tiles in a local storage. Procedure like that is called TileCache. By using the same procedure which used on Google Maps, this research will use TileCache to improve web GIS Scibun application server based performance. This research will compare performance on GIS Scibun before and after TileCache is applied. Measurement variable is amount of loading time of 11 maps on GIS Scibun. Every map gets 4 tests, which are first loading, zoom in, zoom out, and pan map. Each test gets 5 times repetitions. Based on the tests, TileCache reduces average access time almost 100%.
