:<small>Historical note: In 2014, Chrome outperformed Firefox. Changes in Chrome in 2015 reduced its performance for rotating molecules in JSmol. In December, 2015, a change in Chrome (first in version 47) made it unable to rotate molecules in JSmol satisfactorily. As the mouse moved, the molecule remained fixed until the mouse movement stopped, whereupon the molecule jumped to the final position in one step. Bob Hanson was able to work around the change in Chrome with a modification to JSmol, but frames/second are still poorer than they were in Chrome in 2014.</small> | :<small>Historical note: In 2014, Chrome outperformed Firefox.

Tests below were done in [[FirstGlance in Jmol]] in the default HTML5 mode, using [[7ahl]], a single model with 22,778 atoms (which puts it in the largest 5% of entries in the [[PDB]]). Tests were done in a browser window approximately 1,400 x 900 pixels on a late 2014 MacBook Pro (2.2 GHz Intel Core i7 with 1600 MHz DDR3 RAM). With spinning on, the number of frames in 10 sec was counted and divided by 10 to get frames/second. Browsers were the versions current in December, 2015. | Tests below were done in [[FirstGlance in Jmol]] in the default HTML5 mode, using [[7ahl]], a single model with 22,778 atoms (which puts it in the largest 5% of entries in the [[PDB]]).
