 Hello
 
 I have also seen the same result on sparc64 and amd64 kit,  I have
 looked into it a bit on google and the general feeling is that the WCPU
 (or weighted CPU) count is not all that accurate.
 
 A more accurate representation can be obtained by passing the -C flag
 when starting top.  This is for raw CPU rather than a weighted average,
 on some quick tests on a V120 whilst running buildworld I have not seen
 a reading above 100%.
 
 Kind Regards
