Mikrotik hapac2, 6.49
Simple queue to shape traffic for sister PC, mobile and tablet to prevent her youtube or upload traffic interfere with my traffic. All IPs set to static in DHCP server.
ISP bandwidth 1gbit symmetrical, fiber.

 name="shaper" target=192.168.30.11/32,192.168.30.12/32,192.168.30.14/32 dst=WAN parent=none 
      packet-marks="" priority=8/8 queue=ethernet-default/ethernet-default limit-at=0/0 
      max-limit=150M/150M burst-limit=0/0 burst-threshold=0/0 burst-time=0s/0s bucket-size=0.1/0.1 
      total-queue=ethernet-default

If simple queue turned on - getting about 20 mbits when uploading, and lot of Total dropped in Total statistic

If simple queue disabled - getting about 500 mbits.
