The default on i386 is 100 - this is not the case on alpha. > Setting HZ=1000 absolutely destroyed my Alpha's throughput: As long as I can remember alphas default to > 1000. E.g. some are doing 1200 and other 1024 depending on the platform. AFAIK there are reasons not be exactly 1000. Why do you need 1000 instead of the system default? -- B.Walter BWCT http://www.bwct.de bernd@bwct.de info@bwct.de
