MySQL 5.6 takes long time to connect, even with the “MySQL 5.6 Command Line Client”

问题

I have had MySQL 5.6.16 and was working perfect suddenly the MySQL connection become so slow to connect (20 - 21 seconds) I have removed it completely even with the data tables and downloaded and installed ver. 5.6.19 with a fresh and new installation, but this didn't fix the long time connection EVEN with the MySQL Command Line Client it takes 20 seconds to return the "mysql>".

Also any web-based php code with mysql query connection takes 20 sec to get the data page.

I also tried enabling skip_name_resolve / connect_timeout = 10 / wait_timeout = 50 but non of this did anything.

I have: Windows 7 Home Premium SP1 x64 MySQL 5.6.19-enterprise-commercial-advanced Apache 2.4.9 (Win64) OpenSSL 1.0.1f PHP 5.5.10 MySQL Global Status: https://www.dropbox.com/s/gz44pvtomwbncog/MYSQL_GLOBAL_STATUS.txt
