The problem is simple - exhibit is not optimized for front-end performance - you can see the it on this waterfall diagram: http://webpagetest.org/result/090520_266054de45d8f10d3461ae7e7dc0ecaf/
Biggest delay (18.5 seconds) is happening before the data in JSON is even requested on 43-rd request ( http://webpagetest.org/result/090520_266054de45d8f10d3461ae7e7dc0ecaf/1/details/#request43 ). Basically all of the code should be requested in one JS request and all styles in one CSS request, more over in ideal situation no JavaScript should even be loaded or executed before HTML and CSS loads, but it might be harder to achieve. I think bundling techniques that SIMILE projects use (I experience same issues with just Timeline and Timeplot) can be dramatically improved to achieve better performance.
