AMD-K6(tm) 3D processor, Linux 2.6.33.14-rt31-k6 (Profile)

Latency plot of system in rack #8, slot #1
Data to construct the above plot have been generated using the RT test utility cyclictest.
Command line: cyclictest -l50000000 -m -n -p99 -i400 -h800 -q
Total number of samples: 50 million
Resolution of latency scale: reduced 
Duration: 5 hours, 33 minutes
Characteristics of the 20 highest latencies:
