Intel(R) Core(TM) i7 CPU 950 @ 3.07GHz, Linux 2.6.33.7.2-rt30-32 (Profile)

Latency plot of system in rack #b, slot #5
Data to construct the above plot have been generated using the RT test utility cyclictest.
Command line: cyclictest -l100000000 -m -n -a0 -t1 -p99 -i200 -h400 -q
Total number of samples: 100 million
Resolution of latency scale: normal
Duration: 5 hours, 33 minutes, lowest P state: ondemand
Compare latency of primary with shadow system
Characteristics of the 20 highest latencies:
