Intel(R) Xeon(R) CPU E3-1270 V2 @ 3.50GHz, Linux 2.6.32-754.2.1.el6.x86_64 (Profile)

Latency plot of system in rack #0, slot #1
Note that this system runs a non-RT kernel.
Data to construct the above plot have been generated using the RT test utility cyclictest.
Command line: cyclictest -l100000000 -m -Sp99 -i200 -h400 -q
Total number of samples: 100 million
Resolution of latency scale: normal
Duration: 5 hours, 33 minutes, lowest P state: performance
Compare latency of primary with shadow system
Characteristics of the 20 highest latencies:
