Is it always showing 95% utilization? It has been my experience that
many processes on Linux systems are very short-lived; shorter than the
cycle time of top. This is especially true for any machine with a
multi-gigahertz CPU.

When I run make on a large software package, it is obvious from its
output that there are many invocations of the compiler, and the total
CPU usage is quite high, but I may not see any process in top with
greater than 5% CPU. They all (most all) complete between cycles of top,
therefore top will not see those processes. top takes a snapshot of the
system at the time it wakes up. Any process that exits prior to a
snapshot will not be reported by top.

Perhaps you need to look at the rate of process creation: gkrellm can do
this.
