Roo shell slow in Eclipse

We have a project with 15 entities, using GWT.

When starting the Roo-shell in STS it needs more then 10 minutes (consuming 100% CPU) until it executes a command (e.g. "hint");
When starting the Roo-shell from command line (Win-XP), it's just a matter of < 30 seconds...

with the metadata status command I see no big difference between external roo shell and sts-embedded one. maybe it's an STS/eclipse issue?

here are the results of metadata status:
