Re: cached Betriebssystem Results?

Hello Joe, thanks to you and Roedy,

thank you for your answers. It couldn't be JDBC, because the
JUnit Task is "off" during between to runs, the Library with
JDBC Driver is not in use. I could leave eclipse and start
it again, running the JUnit Task (with the SELECT) again,
this tasks duration is again lesser than after starting the
machine and run the Test for first.

Nice Example with an old Lady, buying brooms. I get it ;-)

But the answer to my first question "who caches", would be
"the Operating system". And to the second part, "where can
i disable the cache", the answer have to be: "you can't
without admin rights".

Okay, Windows have a File Cache and what I sighted was the behaviour,
listed on http://www.mckoi.com/database/maillist/msg00502.html
where the poster get the same characteristics even after reboot,
first run takes more time than following.

Unfortunately I have no Admin Rights to clear the File Cache, so
I have to think about making dummy selection between duration tests,
as you supposed as third op****tunity, Joe.

Thanks again, Detlef
