Absolutely.  The plan is to log stream and circuit information on the
tor processes used by Torperf.  See section 2.2.1 "Results format" for

Results may include data which appear not immediately relevant to
measuring Tor performance, but which may be useful for related purposes.
For example, Torperf should include data about circuit failures in its
results, even though these circuits may not have been used in actual

Also see the appendix that specifies data formats for stream and circuit

If you have suggestions for making this clearer, can you send me a patch
to the LaTeX sources?


All the best,
