why run many start_fact_backend process

[chenjianquan7]

it should be one process or many process, system very solw when unpack firmware, what should i optimize performance?

FACT makes heavy use of multiprocessing. One or more worker processes are started for each analysis plugin (the number can be configured in main.cfg). Unpacking a large firmware with thousands of included files may take quite some time. How large is the firmware that you are trying to unpack? You can also adjust the number of unpacking workers in main.cfg (option "threads" in section "unpack"). By default it is set to 4.

Closing as this is working as intended.
