mikrotik rate limit problem

Hi all!

I use pppoe with radius. It’s work fine, but if I example set 1024k/14000k mikrotik-rate-limit for user, then upload bandwidth is OK, download is 8-10M max. If I raise bandwidth (ex: 30M/30M), then user’s download speed doesn’t changed. Without mikrotik-rate-limit the user’s download speed is 20M/20M.

Any ideas?
