It is right : I've let some kernel debug options while performing these tests. I change it right now. Test was launched without any kernel debug options, and we got a worst case of 197µs now. Here is a sum up of our results : [Board] : AT91SAM9261EK [Kernel version] : 2.6.19-at91-xenomai-adeos [Clocks] : CPU 198 MHz, master 99 MHz, main 18.432 MHz [Nucleus latency] : 323µs [Root] : nfs [Kernel debug options] : No [Load Softwares] : calibrator + ping host + bonnie++ [Duration] : > 15h [Best Latency] : 45µs [Average Latency] : 82.5µs [Worst Latency] : 197µs _______________________________________________ Adeos-main mailing list [email protected] https://mail.gna.org/listinfo/adeos-main
