Comment:

I looked at the status.html files for some of the new-downloader runs. It looks like there's a reasonable correlation between download speed and server selection. The 240kBps-ish downloads tend to use sp26/nszi/4rk5, while the 130-140ish downloads tend to use fp3x or sroo instead of 4rk5.

Without more info from the 1.7.1 downloads (data which would be in the download-status, but for the old-downloader it isn't displayed until after the whole download is complete), we can't guess what servers were used for those runs. Zooko, how consistent do you think the speed-difference results would be if you used a 100MB file, instead of using the first 100MB of a multi-GB file? That might let us use Terrell's script and also collect download-status from the 1.7.1 runs.

It'd be awfully convenient if the speed difference that Zooko observed could be attributable to server selection, and if the combo patch made that selection work well enough to ship 1.8.0. A 1.8.1-era improvement could be to try out new servers over the course of the download, so that we'd land in the three-good-servers (sp26/nszi/4rk5) mode more often than the two-good-one-slow-servers (sp26/nszi/fp3x) mode.
