They are the same tests as before. What I was wondering about before is the documentation in the wiki. It's written, that the I-Pipe tracer as shown was activated by latency -f. The trace I did was also taken with latency -f... a mistake in the wiki ? If necessary I can post the logs again, don't know what my tar did there..
