Re: [xwiki-users] Uploading larger files

The problem is memory expense. When you upload an attachment, it is put into RAM, then it's saved in the database, but before the save is committed, the content is copied and converted to a base64 String (expanding it by 30% for the base64 then doubling it because java uses UTF-16 for String) then it is formed into an RCS archive node using Apache jrcs which makes a copy of the content (also in ram). The result is you need memory capacity which is many times the size of the attachment. The short answer is although we are looking at ways to improve memory footprint, currently the effective limit is about 30MB. Caleb Dalluege, Pierre (extern) wrote:
