The defaults are fine for most clients.
And if you change them, you may be less anonymous.
All supported versions of Tor only use the first value in the list:
o Minor features (configuration):
- The "DownloadSchedule" options have been renamed to end with
"DownloadInitialDelay". The old names are still allowed, but will
produce a warning. Comma-separated lists are still permitted for
these options, but all values after the first are ignored (as they
have been since 0.2.9). Closes ticket 23354.
Here's how you can use the authorities less:
1. Make sure you are using the default set of authorities.
(No DirAuthority or AlternateDirAuthority lines in your config.)
2. Avoid using the directory authorities when you're looking for a fallback:
Don't set this value to zero, unless you are willing to fail if the
fallbacks you try are not available.
3. Delay authority fetches until you've checked a few fallbacks:
On a client:
Or however many seconds you're willing to wait if the fallbacks you try are
not available. (You can't make relays stop connecting to the authorities.)
And if you're using 0.3.4.8 or later, then you can spell the option like this:
The old spellings work on all supported Tor versions.
