When a process is running in the system space, it cann't be preempted until it return to userspace, even if the process should be reschedule and other process was ready to run(because the server system close the kernel preempt by default). This schedule delay may impact the performance of waiting process, therefor we introduce the longsys check to collect the schedule delay information of process. The longsys indication could help us spot the possible performance jitter in the system.
