In one version (and I can’t recall which) asterisk moved to an internal timing system, to avoid the hardware need.
There should be quite a lot of discussion of it in the archives or perhaps voipinfo
I don’t know if you can slow the VM processor speed? I am guessing it is counting something much faster than it used to
