OK. This tells us a lot more. Not quite the answer, but very much where to
focus attention.
Immediately after reboot, top reports this (excerpted from what you posted):
8:03pm up 3 min, 1 user, load average: 0.05, 0.15, 0.07
CPU states: 1.9% user, 1.9% system, 0.0% nice, 96.3% idle
1285 root 4 0 444 444 384 S 0 0.0 0.9 0:03
pppoe
Later, when thing slow down, the corresponding elements of top's report read:
6:05pm up 3:22, 1 user, load average: 2.69, 2.78, 2.50
CPU states: 28.5% user, 46.3% system, 0.0% nice, 25.8% idle
1285 root 20 0 444 444 384 R 0 38.6 0.9 29:20
pppoe
Now this would be a bit easier to interpret if these two sets of results
were from the same boot/init cycle (the reported uptimes suggest that they
are not).
But no matter. In the second top report, the only processes using any
appreciable CPU time are pppoe and top itself. So that is where you need to
concentrate your attention ... what is going on with pppoe that causes it
to tie up so much CPU time? I can't help you more specifically there, since
I have neither a PPPoE system myself nor access to one. But you need to
attend to the details of your PPPoE configuration as well as any oddities
in what your ISP does (PPPoE details can vary quite a bit from one ISP to
another).
Don't worry about the larger number of processes in the second listing. It
may be an artifact of how you ddi the printouts. Even if it is not,
processes that use almost no CPU time do not contribute to basic system
slowdowns.
