X-BeenThere: freebsd-questions@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: User questions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 04 Apr 2005 09:17:21 -0000 I read about polling and HZ=1000. The latter is not high enough for vmware3 (it complains..). I read 'man polling' and learn something about this, but I really want to know more about 'hz=1000' The GENERIC has hz=100 as I recall (fbsd-4.11). Can somebody explain I "human language" what happens if you raise this HZ? Is there a processor related issue here? What exectly happens if you have 'hz=1000' or is it maybe better to have 'hz=2000' ? I can't decide now because I don't understand what happens..
