CachedResource contains a StringBuffer m_data. Internally, when data is assigned to the CachedScript and CachedCSSStyleSheet, they decode the m_data buffer, and store the result into a private string (m_script and m_sheet, respectively). Thus, each of these objects has two in-memory copies of the cached object. The m_data is actually not needed and can be removed. The only thing which uses it is the InspectorController; and that usage can be removed with a small amount of work. For www.cnn.com, this led to a 600KB footprint reduction. For www.yahoo.com, this led to a ~2MB footprint reduction. I will post a patch when it's ready. 79944 1 mrowe 2008-05-08 17:27:46 -0700 *** Bug 18956 has been marked as a duplicate of this bug. *** 101514 2 ap 2008-12-05 10:03:56 -0800 Is this still an issue?
