I've also noticed slowdowns recently, I think it's the new ciphers likes
ecdsa. Try this:

Connect using ssh -vvv and examine the output to find which of the
various ciphers and algorithms are used once connection is achieved. On
the client, add those configuration options for the server to
ssh_config. You should notice a speed up on the next attempt as unused
methods will be skipped

man 5 ssh_config

has all the details
