Note that this may well be due to the new load-average code rather than anything else.. You may see artificially high load averages because the place where the load average is computed is different..
The calculations are now done in a bottom half handler ("software interrupt"), not inside the actual timer interrupt - this may well give slightly different behaviour, especially for code that uses network stuff (and select()), because we're now more likely to calculate the load averages at just the moment when any network activity has taken place..
So you shouldn't be worried unless you actually _feel_ that it's slower (remove the "xload" stuff first, because otherwise it will unconsciously make you assume the machine is slower ;-)
