MySQL 5.1.14 SLOW !!!!

Question

Dear All,
i am using CF7.0.1 with MySQL 5.0.14 and JDBC connector
5.0.4. However, it is slow !!
For example: CF need 20 ++ seconds to display a very simple
query result if i am using MySQL 5.0.14 with JDBC 5.0.4.But if i
changed the JDBC connector to ver 3.0.17, CF works as usual.....
Any one know what is the problem?

Now, it's sure, libmysqlclient need to be fixed and qt rebuiled:
#include <QApplication>
#include <QSqlDatabase>
#include <QSqlError>
#include <QDebug>
int main( int argc, char *argv[] )
QApplication app( argc, argv );
QSqlDatabase defaultDB = QSqlDatabase::addDatabase ( "QMYSQL3" );
defaultDB.setDatabaseName( "akonadi");
defaultDB.setUserName( "******" );
defaultDB.setPassword( "*******" );
defaultDB.setHostName( "localhost" );
if ( defaultDB.open() ) {
// Database successfully opened; we can now issue
qDebug () << "ok";
else {
qDebug() << defaultDB.lastError().databaseText().toLatin1();
return 0;
result:
"Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)"
