Hibernate Once Resume Many (HORM) Benchmark

This can serve as a general reference for Windows XP Embedded boot up time performance differences between using Hibernation Once Resume Many (HORM) and standard booting.

The following test were run on a Celeron M 1GHz with a 1G Apacer compact flash card.

1. System with 512MB DRAM memory
Normal boot: 43.7 seconds
HORM boot: 24.2 seconds

2. System with 256MB DRAM memory
Normal boot: 38.9 seconds
HORM boot: 19.9 seconds

The results above should vary depending on the compact flash card being used as well. The important information to look at is not the total time, but the time differential between Normal boot and a HORM boot.
