Using http://localhost:8080 at APEX(11gr1), horrible performance

I had to install a 11g release 1 on Windows for demonstration purpose of APEX. APEX comes standard with 11g, so that's nice. When using Embedded PLSQL you don't even need Apache... But when I'm using http://localhost:8080/apex/apex_admin, the login-page popped up after a minute or two.And every page I use has the same horrible performance. Using the loopback by the way like on the server gives the same result.

Determining compression-factor 11g release 1

Working on 11g, release 1 (, managers wanted to know what kind of compression factor we achieved in the datawarehouse. Amount of (compressed) data: just about 1,5 TB. In all my naivity I thought Oracle delivered the package 'DBMS_COMPRESSION' which will show me the rate of achieved compression per table. But first of all, in 11gr1 there was no package like 'DBMS_COMPRESSION', this is only delivered with release 2.
