Hello everyone!
I'm facing an issue with TCP connections bandwidth between the two CHR.
I have 2 CHR with RouterOS 7.1beta6: one in Russia and one in Kazakhstan, both have a gigabit Internet connection.
Both routers connected with a WireGuard VPN connection. To measure speed I use the bandwidth test tool in RouterOS.
If I use the UDP test - the results are pretty awesome: ~900Mbit for receive and send.
But if I use TCP test:
RU->KZ ~900Mbit
RU<-KZ ~30Mbit
I've done a lot of tests, but cannot figure out where is my issue.
ISP is ok, L2 has no problems, without Miktorik CHR I can get the full speed with no issues.
One of the side effects - I can get up to 140Mbits with TCP test if I use 60+ connections.
Could someone please give me any ideas on how to find the source of my problem?
Thank you.
