As the number of spectra uploaded to ChemSpider increases (and it is now increasing at quite a rate) we have noticed that ther increased loading time associated with records with a large numbr of spectra can be very long, especially if the spectra are “heavy”, for example for C13 specra at high-frequency and with zero-filling. When there are a number of spectra there are even more challenges.

With this in mind we have introduced the ability to Load a Spectrum when the user wants to see the spectrum and not automatically on loading the page. An example is shown here for recently uploaded spectra from the Drexel University laboratory of Jean-Claude Bradley.

Please est it out and let us know if you see any issues. the example listed above has a “heavy C13″ spectrum so loading might take awhile. 

Stumble it!

    I’ll be giving it a good working over this weekend when I add more spectra. This is a great idea, I’ve noticed a bit of a lag with most of the records that contain spectra, I think this will help a great deal.

    The loading issue for the applet should also be resolved shortly when a new lighter spectral display applet goes online for all to see. So, applet download times will be zippy AND you’ll have the option to view or not view.
