Yes, I have been suffering slow download speeds for a few weeks now. Even = with repeated downloads, it is consistently slow. I only just now tried ou= t using `torify wget`, which surprised me since it was much much faster ---= one lucky download even got up to 6MB/s over frikking TOR before I ^Ced it= . I've even tried doing `torify wget` and `wget` in parallel on two separa= te shells --- the `torify wget` was definitely faster, getting anywhere fro= m 100kB/s to 700kB/s with a few outliers at >1MB/s, while `wget` was consis= tently below 40kB/s and eventually settling to ~11kB/s after a few seconds. This holds even for packages I expect to be popular and thus likely to be i= n-cache with high probability, like `linux-libre`. Thanks raid5atemyhomework
