ASA 5506-X police traffic

Hi ,

I have an ASA 5506x and need to throttle down the download link (upload as well but later).

I have tried the QoS policing feature using both input/output and ASA does police but the link is unusable - pings keep dropping when I just open a website, cannot download anything, speedtest shows 10mbps but when I do it, everything stops for a few seconds.

I know policing is a hard way of doing QoS but should it be that bad? Am I missing anything obvious here? As I read, there is no shaping on this device...

With this config, it is usuable. I eve tried this: my link is 100Mbps, I policed it at 90Mbps - got the same result - unusable link dropping everything after loading a basic youtube clip, downloads drop etc. I tried both input/output on inside and outside interfaces - no matter how I combine or or just do one a the time - it is usable.
