There is a lot of CSS on those git pages, I believe some CSS caching is being looked into to reduce the amount of processing required. In my dabblings with building a 68k version of NetSurf for AmigaOS 3, I've noticed that the text layout and rendering code plays a big part in the speed NetSurf loads pages. On AmigaOS 3, rendering outline font glyphs is painfully slow, and I think this is down to the 68k. I notice the Atari code has three font rendering engines; VDI, FreeType and Internal. It look like FreeType and Internal are enabled, and FreeType is the default. Try setting the following in your Choices file: atari_font_driver:internal See if that makes any perceivable difference.
