![]() So system overloaded on 17.65/8*100=220.6%.Multi-tasking ability and faster response time are the most attractive features of Linux machines. in average 17.65 threads waits in run-queue during last 5 minutes.in average 8 threads executed during last 5 minutes.Second number in Load Average = 25.65 on system with 8 cores means: This means the OS scheduler cannot allocate the next time slice to some threads due to the busy cores and puts them in a run queue to wait for execution. System overloaded if Load Average > number of logical cores. One core execute one thread at a time slice.Ĩ cores can execute 8 threads at a time slice. ![]() ![]() Is an average, over some period, number of threads executed + number of threads waiting to be executed. So CPU cores are busy at 98% by all of userspace processes with 79,2% executing two ffmpeg processes.īecause transcoding is a CPU bound task, you will almost always have close to 100% utilization on any CPU. Here 19.9% of user space time + 78.1% of nice time = 98% of CPU usage by userspace program. So two ffmpeg processes utilize all 8 cores at 460.7% + 331.7% = 792.4%. Show utilization - percent of time when CPU is not idle and execute tasks scheduled by OS scheduler.Įach core may used up to 100% so max usage capacity of 8 cores is 800%. I7-7700T have 4 physical cores, and with HT enabled 8 logical cores In top press '1' for per core stat and 't' to turn graph bars. you should check per core CPU statistics to be more accurate.CPU usage and Load Average numbers interpretation depends on number of logical cores.in Linux Load Average also includes processes in uninterruptible sleep state waiting for I/O.total number of physical cores in a system (all CPUs).To interpret CPU usage and Load Average numbers you should take into account You should use load average to evaluate CPU requirement.
