I connect via ssh to the server, it slows down wildly, and apparently only with me. They have Macs, I have Fedora, where to dig?

Question

linux

Connecting is fast, but typing commands takes a hell of a long time.
Other poppies seem to have no problems.
The admin just ignores me, so it seems to figure it out yourself.
But I'm still new to this, I would like to understand the directions where to dig. Internet speed is normal.
ssh -c blowfish-cbc XXX tried supposedly fast cipher algorithm but didn't notice a difference

Answer 1

Made a response.
I would look towards DNS, very frequent problems arise with ssh here.
To check, try UseDNS no in /etc/ssh/sshd_config .
If it will be fast, then it is necessary to consider the reasons in DNS.
