performing well. At higher consumption rates, CPU consumption can become a bottleneck to
good performance.
• When system CPU consumption is significantly higher than process consumption, this may

System Call Rate
This feature displays the rate of HP-UX system calls over time. This metric currently provides
information about three systems calls related to threads:ksleep, kwakeup and sched_yield.
These values are indicative of thread behavior in Java applications. High rates for these system
calls can impact application performance.
