But in that case, the CPU usage should not be reported as 97%. Also, he has
three streams, which as far as I know could result in three threads for
decompression.

Of course, I have no idea what the problem might actually be, so this post
isn't all that helpful. But it does seem that his configuration does take
advantage of the additional processor, and so that would imply that his
problem may not be a CPU bandwidth issue (since he gets the same CPU usage
and performance even after adding a second processor).

I am, of course, assuming that the only difference between his
single-processor and dual-processor test is the number of processors. That
is, that the CPUs used are otherwise identical. I am also assuming that by
"dual-processor" he does NOT mean "a single Hyper-Threaded processor", since
in reality Hyper-Threading adds only a modest amount of processing bandwidth
(10-20% at best in many cases).
