Why does Mikrotik RB2011UiAS-2HnD-IN have a high ping to the modem?

Question

Ping

Good day to all, dear ones. There was a need to distribute the Internet to an average of 50 +/- computers, about 10-15 locally, everything else over the air. It was implemented as follows:
Equipment:
- TP-link td 8961nd
- mikrotik RB2011UiAS-2HnD-IN
Internet access ADSL 8/1M
The Internet is included in eth1, 2-3Eth and wlan1 are combined into a bridge called intranet 192.168.88.0/24
wlan2 and eth4-5 outernet 10.10.0.0/20 with assignment 5 to the interface of the address of the form 10.10.0.100
More precisely in the config. I would be very grateful to everyone who helps to solve this problem.
