/public/datasets page loads 1.5MB resource synchronously with xhr

[ansell]

The /public/datasets page loads a 1.5MB resource synchronously using xhr:

collectory-plugin/grails-app/views/public/dataSets.gsp

Line 107 in 994a320

loadResources("${grailsApplication.config.grails.serverURL}","${grailsApplication.config.biocacheUiURL}");

The resource it is loading is:

https://collections.ala.org.au/public/resources.json

This causes some browsers and some slow internet connections to fail.

In Firefox on MacOS, the warning about using xhr synchronously on the main thread is shown. On IE11 with Citrix (not sure what the underlying OS is), the developer tools are not able to be activated, but it sporadically fails with a message about "script on this page is taking too long".

Won't do before migration to the new infrastructure.

It would be easier to close these issues rather than leaving them open, as the collectory-plugin won't be used in the new infrastructure.
