Intel(R) Atom(TM) CPU E620 @ 600MHz, Linux 3.12.50-rt68 (Profile)

Latency plot of system in rack #7, slot #2
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
Characteristics of the 20 highest latencies:
