Mikrotik CCr1072 performance issue

Hello,
I have a mikrotik ccr 1072 with 2x 10gb LACp , ~110 VLANs , bgp with 4 peer and all of them announce default route to me, and my traffic is about 3gbps outbound and 500mbps inbound and I have 6 firewall RAW rules, 5 filter rules, 1 mangle rule, and I have 2x GRE tunnel and about 200mbps traffic on those gre tunnels, and i assigned ~200 prefixes to my vlan (different vlan) so this is all of the configs that i have on my ccr 1072 and in addition to them connection tracking is also disabled,
the issue is something my cpu load goes to %30 and play around %30~35 and when i disable any vlan once and enable it again the load will decrease to %1-2 ,
i have checked memory and other things and they were ok ,
also when i used Tools → profile i see %40 is for total cores and %20 for networking process and %7 for firewall process and other process are under %1-2
Can someone help me on this and what is the issue?
and I already upgrade both routerboot and ros to 6.45.6
Thank you.
