Hello Tor, hello world! Below you'll find the highlights of Tor metrics team work done in May 2017. On behalf of the Tor metrics team, Karsten Added new visualizations of OnionPerf onion server measurements to the Metrics website [1]. [1] https://metrics.torproject.org/torperf.html?start=2017-03-03&end=2017-06-01&source=all&server=onion&filesize=50kb Experienced a sustained increase in requests to the Onionoo [2] servers from 800/sec ~4k/sec for almost 1 week, which could finally be handled by increasing the number of front-end servers from 2 to 5 and reducing the TLS RSA key size from 4k to 2k. [2] https://metrics.torproject.org/onionoo.html Released metrics-lib version 1.7.0 [3] which adds support for newly added fields in Torperf/OnionPerf files and extra-info descriptors, streamlines some method names, and fixes a few bugs. [3] https://lists.torproject.org/pipermail/tor-dev/2017-May/012261.html Performed an analysis of adding Laplace noise to directory-request statistics to evaluate whether the resulting statistics would still be sufficient for estimating user numbers, but concluded that this still needs more research.
