Where do I have to add this? Also in the catalina.bat?
I tested set CATALINA_OPTS=%CATALINA_OPTS% -Xms1024m -Xmx2048m in
Catalona.bat as mentioned from Thilo Krawietz' email.

Still it seems to be very slow.

Thank you

by setting the environment variable JAVA_OPTS to something like this: 
-Xms32m -Xmx512m
this will cause the vm to allocate 32m at startup and limits the maximum
java heap memory size to 512mb.

you can set the environment variable by adding the following command
somewhere at the beginning of startup.bat:

set JAVA_OPTS=-Xms32m -Xmx512m
