Hi

How I can configure sshd_config to improve the ssh faster?

It is slow to prompt the login

Fix your DNS setup and/or configure it to "UseDNS no". Such slowdowns happen because sshd tries to get a reverse DNS lookup of your IP address.

It can be a big PITA when you try to login into a server to fix a broken DNS and the login times out because it tries to get a that PTR record back......

Just remember the mantra: "most weird network problems are related to DNS problems....."
