[webkit-dev] improving String::append()

Hi, according to my measurements, a large chunk of WebKit memory consumption comes from WebCore::TextResourceDecoder::decode (loader/TextResourceDecoder.cpp:818) which calls String::append (String.cpp:82). The comment there says: // FIXME: This is extremely inefficient. I would volunteer to rewrite the code (especially reducing the memory consumption), but first, I would like to hear your opinion how can we make the string handling of WebKit better. Zoltan
