MySql Connection Really Slow?

If your MySql connection is really slow? Do you think its JDBC or Bandwidth sucking the speed? Are you going crazy checking wireshark for packet problems? Did you see Malformed Packet? Has the server been on for months? Did you get an update?

Before you check all that, make sure your Reverse DNS is setup, so MySql can authenticate you fast. On linux, add your workstation to the list in /etc/hosts 192.168.1.70 workstationHostName.

***** Check Reverse DNS ***** before you get into the deep debugging.
