How is it possible that a 100KB Java application running on the low-end processors of mainstream phones can rival the performance of native code applications running on the fastest mobile processors available? Two words, proxy server. Mini talks to the Internet through a very sophisticated proxy provided by Opera. The proxy does all the heavy lifting – parsing tag soup, re-flowing pages, resizing images and interpreting Javascript. What gets sent to Mini after the proxy has done it’s magic is a compressed binary that requires relatively little processing power to render on the handset. This means that web pages, especially large complex pages with many images, load and render much faster than they would using the phone’s built-in browser. Actually, built-in phone browsers can’t even display pages above a certain size. typically between 30 and 100 KB of combined markup and images. Mini, thanks to the proxy, which splits large pages up into multiple smaller pages, can display virtually any web page regardless of size.
