Memory dump with lime very slow

[e-ferrari]

Hi,
i managed to compile the module and started the dump via:
insmod /root/Downloads/LiME/src/lime-5.14.21-150400.24.69-default.ko "path=/root/ha-idg-1.memory.dump format=lime digest=sha512"
It seems to run, but it's incredible slow. I started it on a HP Server with 160GB RAM. I started it yesterday at 11 pm, today we have now noon (13 hours later) and my memory dump has a size of 1,1 GB ! Following top the system doesn't have much load, the load average is about 7, the CPU is 80% idle and has about 15% IO-waiting.

Any ideas ?

Thanks.

Bernd
