LatencyTOP is a Linux application for identifying operating system latency within the kernel and find out the operations/actions which cause the latency.^[1] LatencyTOP is a tool for software developers to visualize system latencies. Based on these observations, the source code of the application or kernel can be modified to reduce latency. It was released by Intel in 2008 under the GPLv2 license. It works for Intel, AMD and ARM processors.^{[citation needed]}

As of 2021, the project appears inactive with the last commit to the source code in October 2009.^[2]

-'''LatencyTOP''' is a Linux application for identifying system latency within the system and find out the operations/actions which cause the latency.LatencyTOP is a tool for developers to visualize system latencies. LatencyTOP kernel infrastructure measures latencies in the scheduler and tracks it system wide and per process basis. Based on these observations,we can modify the source code of the application to reduce latency hiccups.It was released by [[Intel]] in 2008 under the [[GNU General Public License|GPL]]v2 license. It works for [[Intel]], [[Advanced Micro Devices|AMD]]and ARM processors.
-There are many types and causes of latency. LatencyTOP focus on the latencies which causes audio skipping and desktop stutters. LatencyTOP focuses on the cases where the applications want to run and execute useful code, however, there are some resources that are not currently available. This is done both on a system level and on a per process level. Using the LatencyTOP, we can see what is happening to the system, which process is suffering and which process is causing the delays.
