There is probably something broken in your setup. I have full BGP in
kernel routing table and periodic scanning took just a small fraction of
second. Perhaps you have some excessive logging that slow it down, or
many routes that are unsuccessfully trying to synchronize during each
iteration (usually with 'Netlink: No such process' error in logs)?

Periodic scanning is here mostly to catch problems with normal route
upload and to catch situations when routes disappear because of some
external reason. Probably you can safely set it to several minutes.

If you delete it, default (60 sec) will be used.
