CRS109-8G-1S-2HnD-IN routing issue packet loss

Hi guys

using CRS109-8G-1S-2HnD-IN with routing it loose packets around 1% under moderate load (50kpps, while maximum rating is about 210 kpps from mtk site). Any ideas?

/interface bridge
add mtu=1500 name=loop0
/interface ethernet
set [ find default-name=ether2 ] master-port=ether1
set [ find default-name=ether3 ] master-port=ether1
set [ find default-name=ether5 ] master-port=ether1
set [ find default-name=ether6 ] master-port=ether1
set [ find default-name=ether7 ] master-port=ether1
set [ find default-name=ether8 ] master-port=ether1
set [ find default-name=sfp1 ] master-port=ether1
/mpls traffic-eng tunnel-path
add name=default use-cspf=no
/routing ospf instance
set [ find default=yes ] router-id=172.31.1.103
/ip address
add address=172.18.0.103/24 interface=ether1 network=172.18.0.0
add address=172.31.1.103/32 interface=loop0 network=172.31.1.103
add address=172.16.0.233/29 interface=ether4 network=172.16.0.232
/ip dns
set servers=172.18.0.10
/ip ipsec policy
set 0 dst-address=0.0.0.0/0 src-address=0.0.0.0/0
/mpls ldp
set enabled=yes lsr-id=172.31.1.103 transport-address=172.31.1.103
/mpls ldp advertise-filter
add prefix=172.31.0.0/16
add advertise=no
/mpls ldp interface
add interface=ether4
add interface=ether1
/mpls traffic-eng interface
add interface=ether4
add interface=ether1
/routing ospf interface
add passive=yes
add interface=ether1
add interface=ether4
/routing ospf network
add area=backbone network=172.18.0.0/24
add area=backbone network=172.31.1.103/32
add area=backbone network=172.16.0.232/29

Try this version and upgrade

Now works little better, we lost packets when we have more than 20000 pps

Any chance to know if is an hardware limit or software issue?
