[j-nsp] MX80 Sampling - High CPU

[Scott Granados]

I have 12.3R8.7 running on 2 MX-80s and 2 MX-480s with mixed results.  The good news is the routers will reconverge with sampling enabled now and the PFE programming won’t block hard.  The process is still slow however and while we did some testing it still seems that the processes hang during large updates although they do eventually un-wedge and complete.  The CPU spikes though seem pretty few and far between so that is an improvement.  I’m hoping the rewrite of the sampled and PFE programming in the 13.3 code is improved.  With sampling enabled these boxes reconverge to slowly, especially for modern hardware.
