JSmol/Rotation Speeds

JSmol is used here to mean the HTML5/Javascript (non Java) application working within a web browser (see Jmol has four forms). The "JS" in JSmol refers to JavaScript. JSmol is the default form of Jmol used in Proteopedia. As mentioned in JSmol Notes, JSmol is substantially slower than the Jmol Java applet. With the exception of performance speed, both forms of Jmol have identical capabilities.

ConclusionsConclusions

Firefox outperforms all other popular browsers for smoothness and speed of rotation, and is therefore the recommended browser for websites that use JSmol such as Proteopedia and FirstGlance in Jmol.

DataData

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). 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.
