Hello, i performed some tests on 2.4.20 kernel. what does it mean that instruction count (in phase where packets are put to backlog ONLY ) IS CONSTANT throughout the test while there are 3 to 8 interrupts per packet simultaneously (i can see it on plots)??? [the test is 2 flows. First is 200Kbps and the second 2Mbps. The output bandwidth is 2Mpbs. The first flow is the one i am observing and logging, the other flow is just interference. I use PMC counters to count instructions count.] does it mean that: a) i am measuring sth mispropriatelly? b) interrupts that come when another irq is being processed does not take any instructions??? c) sth. else regards adam ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ oprofile-list mailing list oprofile-list@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/oprofile-list - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
