SCORM

Hi, I'm in the middle of a migration from a previous LMS to Moodle and I'm having a lot of troubles with my SCORMs loading time. As you can see (http://it.tinypic.com/r/2u8j6gl/8) it takes an insane amount of time even to load some small css or images. The total time of loading for the first page is about 35 sec and about 7 sec between page 1 and 2. While loading the same SCORM in the old LMS takes only about 10 sec and less then 1 sec between page 1 and 2 (http://it.tinypic.com/r/107oqdj/8) It's not a server issue because it's the same and I've also tried it locally on my machine. Any hints how to resolve the problem? What could be the causes? Thanks
