Fwd: Query optimisation

[Chris Muller]

Hi Florian, do you have Monticello Configurations loaded?  You need to
load that from impara's SqueakSource repository (add repository
"http://source.imara.de/mc".

THEN, you may load the r40Alpha1 *configuration* from the MagmaTester project.

Hope this helps.
