Simple queues and weird rules

Hi,
Today I had this issue again, when I use simple queues the download speed works fine, but the upload speed only reaches 1/3 of the limit…I configured a simple queue 50M/50M in my RB450G running ROS 6.4 and the download is great, but upload is only 17Mbps…When I disable the queues i get 200Mbps on each direction, so it’s not a pipe limitation.

Any suggestion or similar issue with upload speed?

Anyone else having this issue?

No one else?
