 ||||Go through the Palm changes and consider adopting them. Currently candidates are: Use stack/class memory in CSSParser, use JDCT_Fast for Jpeg decoding (to be achieved with QImageReader to set quality to 49), changes to Cached* to throw away encoded data more early. Palm avoids floating point operation on premultiplied alpha in setRGBA.||||
 ||[https://bugs.webkit.org/show_bug.cgi?id=30740 #30740]||Using QImageReader::setQuality(49) will use JDCT_IFAST and promises to give a 5% speedup on image_cycling.||||
+||[https://bugs.webkit.org/show_bug.cgi?id=30210 #30210]||Create Embedded profile that will tune for embedded usage. This can mean to save memory in favor of speed, add a speed gain by avoiding certain operations, trading image quality for speed||
 ||||~~Image decoder changes needs to be measured. Do they make anything faster/slower? Do they consume more or less memory?~~||[https://trac.webkit.org/changeset/49179 49179ff]||
