Performance

Krona creates graphics and animation with HTML5, which is fairly new technology. Though all major browsers support it, their implementations have performance that is less than ideal. This is likely to change as browsers mature and rely more on hardware acceleration. Until then, there are several factors that can be used to improve performance in Krona.

Browser

The web browser used to view Krona charts is the most important factor in performance. In our tests, Safari and Chrome performed the best.

Window size

Window size is another large factor in the speed of Krona's animations. The smaller the window, the faster it will run. The font size can be decreased to improve labeling of the smaller chart if needed.

Legend

If the chart has a lot of small wedges, the legend (in the bottom right) will have a lot of labels. This can be hidden by clicking the 'x' above it to gain a marginal speed increase.

Collapsing

Leaving collapsing enabled (the default) will avoid causing extra slowdown from increased labeling.
