Estel - i made a few performance tests - switched back and fourth from using the mounted image vs using directly from the partition.

I can say that launching debian applications from the partition is faster in about 5% - 10%, but there is one strange thing i found - chromium is VERY slow and almost non responsive. can that be related to these settings somehow?

when i used your previous image (chromium had a white theme) it worked much faster.

Do you have any idea why?
