> After same research it turned out, that Derby writes multiple gigabyte of temporary files
in its tmp directory during the select statement. Afterwards these temporary files are deleted
and rebuild when the next messages are requested from the message store. The problem is the
PreparedStatement that is used for the select statement. When I changed the PreparedStatement
to a normal Statement the execution time got lower than 10ms. 
> In the attachment you can find a patch, how I fixed this issue. 
> Furthermore you can find a Test-Program (you can import it as a Maven-Eclipse project)
which reproduces this issue. 
> This program creates a derby database with a the activemq Message table and fills it
with data (2000 Messages, this can take several hours). I assumed 3MB for one message as our
messages contain same binary data and has an average size of 3MB.
> After the database a build one time a Statement and one time a PreparedStatment is used
to retrieve the next messages.
> The Statement takes about 1 ms and the PreparedStatement about 258805 ms. Also the second
PreparedStatement takes as much time.
> Here are the temporary files created by derby during the select Statement:

> The exeuction of a cleanup (DefaultJDBCAdapter.doDeleteOldMessages) also took about 6
Minutes.
> But in this case I patched activemq to not do a cleanup at all, as our messages don't
expire.
> I'm almost sure that this issue can be observed in other methodes of the DefaultJDBCAdapter.
But for us it was sufficient to fix it in the recovering of messages.
