Let me know how I can do that and I am happy to perform tests on one of the Gbit boxes. -- Moritz Bartl https://www.torservers.net/ ___ tor-talk mailing list tor-talk@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-talk

And if you profile but you don't notice a difference, try cranking the TokenBucketRefillInterval down to 10 msec or so, and seeing how the profile looks then. :) cheers, -- Nick ___ tor-talk mailing list tor-talk@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-talk

If somebody could profile their relay (ideally before-and-after) to learn whether this is a theoretical concern or a practical concern, that would be great! --Roger ___ tor-talk mailing list tor-talk@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-talk
[tor-talk] Tor 0.2.3.5-alpha is out
Tor 0.2.3.5-alpha fixes two bugs that make it possible to enumerate bridge relays; fixes an assertion error that many users started hitting today; and adds the ability to refill token buckets more often than once per second, allowing significant performance improvements. https://www.torproject.org/dist/tor-0.2.3.5-alpha.tar.gz https://www.torproject.org/dist/tor-0.2.3.5-alpha.tar.gz.asc Packages will be out in a few days. Changes in version 0.2.3.5-alpha - 2011-09-28 o Security fixes: - Bridge relays now do their directory fetches inside Tor TLS connections, like all the other clients do, rather than connecting directly to the DirPort like public relays do. Removes another avenue for enumerating bridges. Fixes bug 4115; bugfix on 0.2.0.35. - Bridges relays now build circuits for themselves in a more similar way to how clients build them. Removes another avenue for enumerating bridges. Fixes bug 4124; bugfix on 0.2.0.3-alpha, when bridges were introduced. o Major bugfixes: - Fix an "Assertion md->held_by_node == 1 failed" error that could occur when the same microdescriptor was referenced by two node_t objects at once. Fix for bug 4118; bugfix on Tor 0.2.3.1-alpha. o Major features (networking): - Add a new TokenBucketRefillInterval option to refill token buckets more frequently than once per second. This should improve network performance, alleviate queueing problems, and make traffic less bursty. Implements proposal 183; closes ticket 3630. Design by Florian Tschorsch and Björn Scheuermann; implementation by Florian Tschorsch. o Minor bugfixes: - Change an integer overflow check in the OpenBSD_Malloc code so that GCC is less likely to eliminate it as impossible. Patch from Mansour Moufid. Fixes bug 4059. o Minor bugfixes (usability): - Downgrade log messages about circuit timeout calibration from "notice" to "info": they don't require or suggest any human intervention. Patch from Tom Lowenthal. Fixes bug 4063; bugfix on 0.2.2.14-alpha. o Minor features (diagnostics): - When the system call to create a listener socket fails, log the error message explaining why. This may help diagnose bug 4027. signature.asc Description: Digital signature ___ tor-talk mailing list tor-talk@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-talk
