Troubles with PCQ rate

I’m using mikrotik as shaper. Created the following rules:
/queue tree
add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=0
max-limit=0 name=Total_download packet-mark=“” parent=ether1 priority=1
add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=0
max-limit=0 name=Total_upload packet-mark=“” parent=ether2 priority=8

/queue type
add kind=pcq name=PCQ_down_100M pcq-classifier=dst-address pcq-limit=200 pcq-rate=100000000 pcq-total-limit=2000

/queue tree
add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=0
max-limit=0 name=Bezlim_100M_download packet-mark=Bezlim_100M_traffic
parent=Total_download priority=8 queue=PCQ_down_100M

/ip firewall address-list
add address=172.16.16.7 comment=“” disabled=no list=Bezlim_100M

/ip firewall mangle
add action=mark-connection chain=forward comment=“Mark traffic bezlimit 100M”
disabled=no new-connection-mark=Bezlim_100M_conn passthrough=yes
src-address-list=Bezlim_100M time=0s-1d,sun,mon,tue,wed,thu,fri,sat
add action=mark-packet chain=forward comment=“” connection-mark=
Bezlim_100M_conn disabled=no new-packet-mark=Bezlim_100M_traffic
passthrough=no time=0s-1d,sun,mon,tue,wed,thu,fri,sat

And we see the following situations:

When applying in address-list rule “add address=172.16.16.7 comment=”" disabled=no list=Bezlim_100M", traffic can not exceed more than 22-23 Mbit. When disabled address-list rule - traffic up to 80-85Mbit.

In what may be the problem? Cpu load ~50%. Mikrotik version 4.5 (in this version good working API).
