Thought I should do a quick recap of what's going on: Kritzkast are now feeding data from their most popular server The API is now limited to 20 requests/sec Heatmap rendering is now 400% faster, on average. Chrome will now rerender repeatedly during a slider event, instead of when sliding is finished (Firefox goes crazy if this is enabled). API responses are now 100% faster, on average. The victims/killers display modes now have buttons. The map list is now paginated, allowing you to browse. Enabled client side cache of data responses. Flicking between display modes (and different maps repeatedly) should be a lot faster now. The site is now responsive and should work at lower screen widths. Data providers are now acknowledged. Cleaned up the code base slightly, still needs a lot of work The amount of data from maps such as Upward is becoming overwhelming and is actually quite difficult to analyze because of it, therefore I've decided to go ahead an implement a default filter of 3000 deaths (when filters are complete) to ensure that the data is still readable. This filter can be removed at the user's discretion.
