watch 'ps axf | awk "{ if ( \$3 !~ /S/ ) { print; } }"'
The processes that aren't sleeping count toward your load. The above
command will print non-sleeping processes. If I'm not mistaken, that
will tell you what's causing the load regardless of whether it's
contention over CPU, IO, or other causes.
You can get similar data from "top" if you tell it to sort by process
status ( F, w, Enter ) and then reverse the sort ( R ).
