Intel(R) Atom(TM) CPU N455 @ 1.66GHz, Linux 2.6.32-754.3.5.el6.x86_64 (Profile)

Latency plot of system in rack #3, slot #6
Note that this system runs a non-RT kernel.
Data to construct the above plot have been generated using the RT test utility cyclictest.
Unexpectedly long latencies may be caused by SMIs
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
Compare latency of primary with shadow system
Characteristics of the highest latencies:
