I just did a quick test on a PC without Qt installed. I'm in
Australia, and my current default mirror is ftp.jaist.ac.jp

During the "Preparing meta information download..." phase, Resource
Monitor told me that the data is crawling in at 10 Bytes per second
(yes, bytes), and it took a few minutes to get the meta info. However,
once I get past that stage, the actual Qt Creator files come in at
~300 KiB per second. Resource Monitor reports that both sets of
downloads came from the same mirror, so it's not just a connection
issue.

I wonder what's the reason for this huge discrepancy? Is it because
the meta information comes in as lots of tiny files?
