I'm trying to organize http/s traffic shaping, what am I doing wrong?

Question

Shaping

Hello! I set myself the task - to learn how to shape http / s traffic, and in such a way - that the pages would be loaded quickly, and whoever tried to download something - it was slow. Marked by the connection-bytes parameter, i.e. 0-512 kb. marked for fast opening (fast web serf), and slow marked and made connection-bytes 513-999999999 kb. (slow web biggest files) Yes, I forgot to mention, it was mark packets and not mark connections. Is everything correct at this stage?

Next, I created the first PCQ queue, specifying the classifier in it - dst.address. And the second, the same, only the limit was made smaller, and the classifier is the same - dst.address

Next, I created a Queue Tree rule, specifying the global parameter, marking (fast web serf), the PCQ queue that I created first. Then the second Queue Tree rule, where the parent parameter (the first entry, instead of global), packet marking (slow web) is the second PCQ queue created earlier with a limit, and indicated a limit of 512K on it.

Next, began tests that were unsuccessful. That is, large files are poured just as quickly. Large file limit doesn't work. I decided to check with the speedtest service. And so download - without restrictions. and upload 512k. And I need both that and that was 512. In addition to opening pages.

PS and the labeling of the bags was indicated by Forward. and mark packets
PSS PCQ - specified dst.address classifier, (like for download)

In general, how to do it right? :) Thanks in advance!
