Design and implementation of in-memory WebGIS based on Linux
基于Linux的内存式WebGIS设计与实现

From the perspective of computer storage systems,a new idea to speed up WebGIS response was presented,which used memory as data storage instead of normal hard disk to solve the I/O bottleneck problem of hard disk.To solve the volatile problem of RAM and develop in-memory WebGIS,a solution based on tmpfs and initrd was offered after analyzing three types of ramdisk techniques(ram disk,ramfs,tmpfs) in Linux and the composition of Linux operation system.The system composition,framework and memory usage strateg...
