You could easily try out by backing up your /home to an external

Ext4 is still in development. I can't cite but I've seen tests where
the performance was very similar to ext3 in terms of speed. Mostly
depending on the file size you have some little advantages here or
there. That was 2 or 3 months ago.
Being in development also means there can still be errors, you should
