330 | The workqueue tracer provides some statistical information | ||
331 | about each cpu workqueue thread such as the number of the | ||
332 | works inserted and executed since their creation. It can help | ||
333 | to evaluate the amount of work each of them has to perform. | ||
334 | For example it can help a developer to decide whether he should | ||
335 | choose a per-cpu workqueue instead of a singlethreaded one. | ||
