Kernel memory usage

I compared memory usage of FreeBSD and OpenBSD kernel (only base stuff running like init, ttys ...).

FreeBSD:
uncompressed kernel size: 13.8MB ( + 46.3MB of modules)
memory usage: 20MB

OpenBSD:
uncompressed kernel size: 8.6MB (no modules)
memory usage: 34MB

Why FreeBSD with bigger kernel uses less memory than OpenBSD?
