Whenever I click on a link to a PDF, I have to wait a long time - typically several minutes - before anything appears. The same links come up almost immediately when using Safari. It seems to affect all PDFs from all sources. Normal web pages typically appear more or less instantly.
The issue could arise because of a pdf plugin installed onto the browser.
This could happen when installing a PDF reader or editor like PDFXChange for instance.
Thanks for these test sites. My access times were, in the order of your list, 29 sec, 4 sec, 3 sec. Don’t really know what to make of this, but (a) all of them were faster than I usually get, and (b) 29s for a 3.82kb file! By the way my download speeds for HTML are all “instant” unless there’s a problem with the site I’m accessing, so it isn’t broadband speed.
