PowerPC Freescale MPC5200 @396 MHz, Linux 2.6.33.7.2-rt30linux_bsp_1.1 (Profile)

Latency plot of system in rack #2, slot #5
Data to construct the above plot have been generated using the RT test utility cyclictest.
Command line: cyclictest -l100000000 -m -n -p99 -i200 -h400 -q done
Total number of samples: 100 million
Resolution of latency scale: normal
Duration: 5 hours, 33 minutes
Compare latency of primary with shadow system
