Cannot Control ICMP Traffic

Hi

I wrote following code , my objective was to restrict bandwidth for ICMP ( Ping ) Traffic -

/ip firewall mangle
add chain=prerouting protocol=icmp action=mark-connection new-connection-mark=mark-icmp  passthrough=yes
add chain=prerouting protocol=icmp action=mark-packet connection-mark=mark-icmp new-packet-mark=marked-icmp passthrough=no

/queue tree
add burst-limit=0 burst-threshold=0 burst-time=0s limit-at=10M max-limit=20M name=ICMP-CONTROL packet-mark=marked-icmp parent=global priority=1 queue=default

I am confused , that whenever I enable the queue tree , http surfing is getting dead slow .
Can anybody explain it ?
