Description:
Using libmysql.dll version 5.5.32 or 5.6.19 under Windows 7 Ultimate SP1 32bit leads to very slow work and delay of 20-30-40 seconds before each execution.
When replace it with libmysql.dll version 5.1.41 all works fine and fast.

How to repeat:
Just use under Windows 7 Ultimate SP1 32bit libmysql.dll version 5.5.32 or 5.6.19

Suggested fix:
Replace libmysql.dll version 5.5.32 or 5.6.19 with libmysql.dll version 5.1.41.

Not need of special tables or database. Just try to execute mysql.exe [mysql  Ver 14.14 Distrib 5.6.19, for Win32 (x86) from mysql-5.6.19-win32.zip, from http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.19-win32.zip] and it will delay with 20-30-40sec before to execute (because use libmysql.dll )

Thank you for the feedback. Why do you think the mysql.exe from package you
have mentioned uses libmysql.dll?
