I've just tried this from the Sanger ensembl website, and that
particular region wasn't particularly fast to load -- took something
like 10 seconds with no DAS sources at all.  Adding several
of the standard DAS sources only seemed to add a couple of seconds
to that.

It does, indeed, appear to be a fairly `busy' region.  I tried
a few other regions of the same length and they returned much
quicker (and again, adding DAS made no more than a second or
two of difference)
