I have no idea how you get "1.5 GB" as the potential data size.

This data (JS/CSS) is only created once for every version of Horde  
and/or application that is installed.  Assuming you have several  
upgrades during the year, that is on the order of *maybe* 10 MB, not  
1500.

As a developer, I haven't cleaned my static directory out since April.  
  Running git, *every* time a theme or javascript file is changed it  
needs to rebuild the static file.  And my directory is at 27 MB:

slusarz at bigworm % du -BM .
27M     .
