[quagga-users 14928] Disable BGP general scanning, BGP SCAN-TIMER

Hi all

I have such a question.

quagga-0.99.23.1, 4 bgp-peers, no IGP, only static, 4 core processor, 
all NIC's interrupts are evenly distributed between processor cores - 
all loads are defined and distributed between processor cores :)

686579

But once every minute for about 3-10 seconds there is a "BGP general 
scanning", which is arbitrarily executed on any of the processor cores 
and loads it 100% within a specified time.

2018/02/14 18:40:41 BGP: Performing BGP general scanning
2018/02/14 18:40:42 BGP: scanning IPv4 Unicast routing tables

Question:

1) Can I turn off (disable) "BGP general scanning" (command 'bgp 
scan-time <5-60>') ? Is this a good idea in my case ?

2) Can I perform "BGP general scanning" on a specific processor core, 
not chaotic ?
