It should be noted that this preconditioning of the matrix heavily depends on the actual contents of it (including time until convergence) and hence using random data is not at all a useful testcase, it would be better to initialize the matrix with some known values. I bet that's also the reason why Windows is so much faster here, its random generator is fairly low quality. As this is a mobile processor: does anything change if you disable any powersaving (just so to rule out on obvious reason for slowdowns)? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
