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.. So, anybody? -- dick -- http://nagual.st/ -- PGP/GnuPG key: F86289CE ++ Running FreeBSD 4.11 ++ FreeBSD 5.3 + Nai tiruvantel ar vayuvantel i Valar tielyanna nu vilja
