I gave SELECT privilege to a user on a particular database, Now whenever I try to connect remotely

$ mysql -h ip-of-remote -u username -p

with that user credentials and try to change the database it takes to long to get Database changed while it connects (goes mysql prompt) very fast

mysql> USE db_name;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed

On the contrary, when I ssh the mysql server and then try to login mysql prompt locally (without host) with the same user credentials and then try to change database it quickly changes and I don't get that message

mysql> USE db_name;
Database changed

I tried to --disable-auto-rehash in my.cnf but no luck. Please help

    Did you try $ mysql -A -h ip-of-remote -u username -p? Apr 30, 2015 at 21:00
  • On doing that I don't get the delay and that message. But I can't recommend that to every user to append -A every time. I need something at the server configuration level Apr 30, 2015 at 21:02
  • I see, then you should restart the server after adding no-auto-rehash to the cnf file Apr 30, 2015 at 21:03
  • Already restarted after making those changes Apr 30, 2015 at 21:05
  • I'd guess your database host tries to resolve your IP address to a host name or vice versa because of privileges attached to hosts. Wild guess, but you might want to check your DNS setup and/or use ip-addresses/host names when granting privileges. Apr 30, 2015 at 21:16

since the the following command use my_database; executed too fast when you try this locally (on the same server), and take a log time when you executed remotely, there is some common causes for that like the connection between the server and client is slow, or there is a delay (lag) on attempting to retrieve and verify reverse DNS, you can try to add the following parameter skip_name_resolve for testing to my.ini or my.cnf under [mysqld] section.
