Yes. FreeBSD has the following comment (in sys/conf/NOTES): # The granularity of operation is controlled by the kernel option HZ (default # frequency of 1000 Hz or a period 1ms between calls). Virtual machine guests # use a value of 100. N.B. It would be nice if there were a (MI) boot option that could be used to influence HZ without recompiling. Booting into ddb and patching hz and a few derived variables isn't that comfortable.
