<p> +Torperf can produce two output files: <tt>.data</tt> and +<tt>.extradata</tt>. +The <tt>.data</tt> file contains timestamps for request substeps and the +byte summaries for downloading a test file via Tor. +The document below shows an example output of a Torperf run. +The timestamps are seconds and microseconds since 1970-01-01 +00:00:00.000000. Torperf can be configured to write <tt>.extradata</tt> files by attaching a Tor controller and writing certain controller events to disk. -The content of a <tt>.extradata</tt> line is shown in the lower part of -the document below. -The first column indicates if this circuit was actually used to fetch -the data (<tt>ok</tt>) or if Tor chose a different circuit because this -circuit was problematic (<tt>error</tt>). -For every <tt>error</tt> entry there should be a following <tt>ok</tt> entry, -unless the network of the Torperf instance is dead or the resource is -unavailable. -The circuit build completion time in the <tt>.extradata</tt> line is the -time between Torperf sent a SOCKS request and received a SOCKS response in -the <tt>.data</tt> file. -The three or more hops of the circuit are listed by relay fingerprint and -nickname. -An <tt>=</tt> sign between the two means that a relay has the <tt>Named</tt> -flag, whereas the <tt>~</tt> sign means it doesn't. +The format of a <tt>.extradata</tt> line is similar to the combined format +as specified above, except that it can only contain "Additional +information" keywords. </p>
