Interpolating from those load figures, you'll probably have
to wait for 5 to 10 more hours ;)

It looks like you were testing the machine /very/ close to
the thrashing point and the garbage collection afterwards
pushed it right over the edge.

One possible solution to speed things up would be to send
-SIGSTOP to 90% of the oracle processes and wake them up
again slowly later on... (this is basically what thrashing
control in an OS does, suspend processes and wake them up
again later)
