the problem is disk activity, not cpu load. nice won't help much.

the most disk-intensive of the anacron jobs are checksecurity and
updatedb, because they have to scan all the filesystem. i suppose it's
better not to remove checksecurity, but you can easily disable the
updatedb script - grep about in /etc/cron.daily .

if your machine acts just as a router, maybe the best thing is to reduce
the filesistem complexity by removing unnecessary packages.

you can also edit /etc/crontab to move the anacron jobs to different
