This paper attempts to analyze the boot-up time of bootloader and Linux Kernel, and to compare performance of several root file-systems for fast boot-up time in the Embedded Linux. Therefore, it was implemented with time measurement module to analyze the boot-up time of bootloader and Linux kernel, and measured the time at each event point related to boot-up. As a result of analysis of six cases packaging, it has turned out the fact that the data checksum routine, decompressing the kernel and ramdisk image takes most of the boot-up time. Root file-system was packaged through analyzing such performance as boot-up time, memory usage, filesystem size. This is based on raw-kernel image and a combination of CRAMFS and JFFS2, and it has small size of the root file-system, the boot-up time is decreased.
