 **Chrome: Overall performance is good. Both spinning and rotation by mouse are a little jerkier than in Firefox (less than two-fold difference).
 **Safari: Overall performance is good. Spinning and rotation by mouse are a little smoother than Firefox for cartoon rendering. For spacefill rendering, spinning was jerkier than Firefox by about three-fold.

+===JSmol (Javascript)===
+All browsers were updated to the versions current at the time of testing (March, 2017). Tests below were done in [[FirstGlance in Jmol]] in the default HTML5/javascript mode. In order to slow down rotation to enable manual counting of frames/second, a large molecule was used: [[1g3i]], a single model with 45,528 atoms (which puts it in the largest ~2% of entries in the [[PDB]]). Tests were done in a browser window approximately 1,900 x 1000 pixels on a late 2014 MacBook Pro (2.2 GHz Intel Core i7 with 1600 MHz DDR3 RAM).  Windows 10 was a virtual machine (VMware) on the Mac, running at native speed on the Mac's Intel processor. For spinning, frames/second were determined at zoom 170%. For rotation by mouse, frames/second were determined at zoom 100%, cartoon rendering.
