what is the use of rate limit in the server profile tab of the hotspot ?
Where exactely do you see this setting?
I checked the helppage, but it wasn’t mentioned:
https://help.mikrotik.com/docs/pages/viewpage.action?pageId=56459266
If it has to do with the wireless device:

I add limits but I don’t see any change
Please explain to me the usage?

Seems that the help page is not up to date yet, the wiki is:

Rate limitation in form of rx-rate[/tx-rate] [rx-burst-rate[/tx-burst-rate] [rx-burst-threshold[/tx-burst-threshold] [rx-burst-time[/tx-burst-time]]]] [priority] [rx-rate-min[/tx-rate-min]] from the point of view of the router (so “rx” is client upload, and “tx” is client download). All rates should be numbers with optional ‘k’ (1,000s) or ‘M’ (1,000,000s). If tx-rate is not specified, rx-rate is as tx-rate too. Same goes for tx-burst-rate and tx-burst-threshold and tx-burst-time. If both rx-burst-threshold and tx-burst-threshold are not specified (but burst-rate is specified), rx-rate and tx-rate is used as burst thresholds. If both rx-burst-time and tx-burst-time are not specified, 1s is used as default. rx-rate-min and tx-rate min are the values of limit-at properties
