Seems the help of --num-threads does not say it exactly:
[--num-threads THREADNUM]:
Using multiple threads to read and compress data of each page in parallel.
And it will reduces time for saving DUMPFILE.
This feature only supports creating DUMPFILE in kdump-comressed format
from
VMCORE in kdump-compressed format or elf format.
Lzo is also a compress method, it should be mentioned that --num-threads only
supports zlib compressed vmcore.
Also worth to mention about the recommended -d value for this feature.
Thanks
Dave
