Intel(R) Xeon(R) CPU E31220L @ 2.20GHz, Linux 3.18.43-rt46-fulldebug (Profile)

Latency plot of system in rack #b, slot #0
Note that this system runs a non-optimized debug 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: ondemand
Characteristics of the 100 highest latencies:
