Hi, to test how dillo behaves on huge pages, I downloaded the mysql manual as a single html page: http://downloads.mysql.com/docs/refman-5.1-en.html.tar.gz With this page I noticed that the drawRegion in FltkViewBase can grow pretty large which slows down loading the page. Attached patch limits the size of the drawRegion to 16 rectangles. With this patch (and HUGE_FILESIZE in cache.c increased to 16M) dillo works pretty well on this huge page. Better than dillo1 and firefox! One problem is that clicking on anchor links (to anchors within the page) reloads the page which take some time. Also memory usage gets pretty high (250M with images disabled). I'm experimenting with reducing the size of struct Word in textblock.hh by moving the highlight stuff out of struct Word and into Textblock. This brings memory usage down to 199M. However, I don't know the highlighting stuff enough to be sure I don't break anything. This probabely falls into the "premature optimization" category anyway. Cheers, Johannes
