The 2 seconds is required for the PubChem query. Apparently that's a much
more involved search than NCI. Here is the same, but from NCI:
http://chemapps.stolaf.edu/jmol/jsmol/liteNCI.htm On my iPhone that loads
extremely fast. (OK, I'm on a network here, but when I switch to 3G, I
don't notice more than a split second difference.)
So the point of this is that for those wanting the flexibility of having a
mostly nonscriptable small model to twiddle that is in MOL file format
(think "PubChem"), JSmol is still a great way to go. You can build this
into any page and just basically "flip a switch" to reload the page using
full-blown Jmol. JSmol will take care of finding the file on your server or
database.
If your server is gzip-compressing JavaScript files, then the bandwidth
comparison is this:
JSmol/full: 500K
JSmol/lite: 45K
Otherwise:
JSmol/full: 2.0 MB
JSmol/lite: 130KB
If someone wants to experiment with this, extending it in different ways --
maybe CIF files or PDB files or XYZ files, feel free. Just write some sort
of JSmol.lite.xxx.js extension. I think I've done what I want to do with it.
