[Pharo-project] Starting with 1.2.1 - Slow installing packages

Hi all, I downloaded 1.2.1, and I'm trying to install some packages to start a new project. The problem I found for the moment, is, thath is taking a lot of time to install. For example, I did the ConfigurationOfO2 and this was 25 minutes ago. Is this normal? I can see pharo.exe is consuming 35MB of RAM. Probably is a limit, and I can increase it? I suppose thath this is the bottleneck. Thanks.
