Performance of JSmol depends on the underlying performance of the javascript in the browser being used. With smaller macromolecules (under about 2,000 atoms) performance is generally good in all browsers except Internet Explorer. With larger macromolecules, the choice of browser becomes more important for optimal performance. | Performance of JSmol depends on the underlying performance of the javascript in the browser being used.

Browser javascript performance varies as new browser versions are released. Below are rotation speed results obtained at various times. | |||

==Conclusions== | ==Conclusions== | ||
===Update April, 2021=== | |||
Versions current in April, 2021, of the '''Chrome, Edge, Firefox and Opera''' web browsers all seem equally good for JSmol. '''Safari''' is acceptable, but rotation of solid (spacefilled) renderings is substantially slower/choppier than the others, especially at high zoom levels. | |||
===Update January 2019=== | |||
Differences from July, 2017: | |||
*Chrome is now faster than Firefox; slightly faster on Mac but 2-fold faster on Windows. | |||
*Opera now performs nearly as well as Chrome (in both Windows and macOS). | |||
*Safari is now 5X slower than Chrome for spacefilled rendering. This is true in OS 10.10 and 10.14. | |||
As before: | |||
*Waterfox is comparable to Firefox for JSmol, and very fast with Java. | |||
*Edge is about 5X slower than Chrome. | |||
*Internet Explorer is 10X to 30X slower than Chrome. | |||

====FirstGlance in Jmol==== | |||
Previously, this section reported that [[FirstGlance in Jmol]] version 2.74 (and several earlier versions) was very slow to load and display large RNA structures. This was due to a bug in FirstGlance that was fixed in [https://oca.weizmann.ac.il/oca-docs/fgij/versions.htm version 2.8 released May 29, 2019]. | |||

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. | All browsers were updated to the versions current at the time of testing (March, 2017).
