I need to think about your other comments. parisc-linux is less than optimal for cache behavior. Especially kernels that predate 2.6.10-ish timeframe where James Bottomley fixed up some of the worst offenses. But if it's an OS problem (it could be), running lmbench on both HPUX and parisc-linux might shed light on where the issue is. thanks for posting the HPUX NBench results. grant _______________________________________________ parisc-linux mailing list parisc-linux@lists.parisc-linux.org http://lists.parisc-linux.org/mailman/listinfo/parisc-linux
