Not so idiosyncratic. I do the same thing with files I get from clients.

I have had a look at them and it appears you have an overabundance of anchor
points, which can add a lot of overhead when processing. This is not uncommon,
especially from programs that produce poor postscript. In general those
graphics are very simple in form.
I would suggest you have a play with the Simplify (Object > Path > Simplify)
function to remove excess points and make better bezier curves. Otherwise you
can remove individual anchor points, but given the large number that could be

It does run in the background. It is especially annoying if there is a
firewall that prevents access to the Adobe site (as I have).
