Of course there are huge advantages to using JSmol:
*Users of a JSmol website do not need to install [[Java]] (which is a [[Java#Java_is_a_security_threat|likely security risk]]).
*Users of a JSmol website do not need to install [[Java]] (which is a [[Java#Java_is_a_security_threat|likely security risk]]).
*The very popular Google Chrome browser no longer supports Java.
*The very popular Google Chrome browser no longer supports Java, nor does Edge (the new browser in Windows 10). Opera plans to remove support for Java.
*A JSmol website will likely work on iPads and smart phones. (Java is not available for these platforms, so Jmol is not an option for them.)

*Proteopedia loads only amino acid alpha carbon atoms (or nucleic acid phosphorus atoms) and ligand atoms, since its ribbon view (secondary structure schematic) works fine without the other atoms. A prominent message is displayed that a ''simplified model'' is being shown, and there is a button to load the complete model. For registered users who are logged in, Proteopedia has a preference setting that will use Jmol_S instead of JSmol.

====Poor performance in Internet Explorer, Edge and Opera====
====Poor performance in Internet Explorer & Edge====
 
JSmol runs in the javascript of the browser (HTML5). Different web browsers operate JSmol with very different performances. '''Chrome runs JSmol best''', Safari is good, and Firefox is usually OK (see note under table below). '''Internet Explorer is unacceptably slow''' (all versions, including version 11), and [http://www.netmarketshare.com it is the most widely used browser]. In '''Opera, rotation of the molecule is slow and jerky'''.
 
*FirstGlance in Jmol detects the browser being used, and recommends a different browser when being displayed in Internet Explorer or Opera.


The findings below are based primarily on tests with [[FirstGlance in Jmol]], and possibly results may be different for other JSmol websites.
JSmol runs in the javascript of the browser. Different web browsers operate JSmol with very different performances (see [[JSmol/Rotation Speeds]]), and the performances vary as browser versions are updated. '''Internet Explorer has always been unacceptably slow''' (all versions, including version 11), but since early 2016, it is [http://www.netmarketshare.com no longer the most widely used browser].

FirstGlance in Jmol detects the browser being used, and recommends the optimal browser when another browser is used.
The above snapshot is taken from [[FirstGlance in Jmol]]. For more details, see the [http://bioinformatics.org/firstglance/fgij/notes.htm#browsers Notes for FirstGlance].
