Yes. Now kdump is in a phase where people are doing scalability work. And
one of the problems is that on mutli tera byte machines, filtering is
taking long time. With-in filtering it is especially the compression which
takes the longest (hatayama and cliff wickman have done some study here).

So Idea seems to be that bring up more cpus in the second kernel and try
to parallelize compression work and try to save dump time of multi tera
byte machines.

Thanks
