Performance problems with executeUpdate

Hi All,

I'm experiencing performance issues under MySQL 5.6.10 (and also tested under 5.5.24).

Running a bunch of DDL statements for bootstrapping the application, I've found that something simple as:

Statement drop = conn.createStatement();
long time = System.currentTimeMillis();
drop.executeUpdate("DROP TABLE TEST");
System.out.println("took: "+(System.currentTimeMillis() - time));

Takes in average 300 ms.

The full bootstrap of the application takes about 15 seconds while that the same code for SQLServer, Oracle and Postgres takes about 2 ~ 4 seconds.

The (drop) executeUpdate statements in the other engines take about 1 ~ 10 ms.


Any Ideas?
