Certainly, however, I am testing this meme now, and it has validity. I,
right now, pulled the latest version of Tor to a Linux machine in Iran and
did a comparative measurement of throughput with and without. Although the
download started out reasonably fast, after a few seconds it seems probably
that my connection was throttled down. Whereas without Tor, my throughput
averaged 84.81 Kbps, with it is currently 14.66 Kbps and rapidly dropping.
If anyone doubts that Tor's overhead is that high, at some point I could
keep tearing down connections and narrow the likelihood of a poorly
performing bridge. However, factually, Tor is slow.
