After using squirrel for migrating a DB from Oracle to Postgres the startup time is now about 20minutes on a P4/3.0GHZ System with 2Gbyte of Ram. Because of the long startup times i tried to reinstall it, but with no effects. I installed it on another maschine (same specs), and after some time the same effect took place. The startup process is very slow. I searched for files which maybe have gotten big during the migration task and didn´t found anything.
I also tried tuning the xm* parameters inside the startup batch file, and also no effects.
