Linux Slab distributor (1) -- Overview C ++ Library Study Notes-memory pool implementation I did some tests: I found that there is no significant difference in the use of memory pools in linux, but there are only two times (this is easily overwritten by computing) Linux memory processing mechanism is good. Generally, there is no need to use a memory pool ??? I don't know what you think. Speed test: In

First, the application scenarioFirst, it must be made clear that the thread pool is not omnipotent and that it has its own specific usage scenarios. The thread pool is used to reduce the impact of the overhead on the application performance of the threads themselves, but only if the cost of creating and destroying the thread itself is not negligible compared to the overhead of the thread execution task . If

Using the thread pool for optimal resource utilization the most common problem in the Java Multithreaded Programming Forum is the various versions of the "How can I create a thread pool?" "In almost every server application, there are problems with thread pools and work queues. In this article, Brian Goetz shares the thread pool principle, basic implementation an

Principles and usage of java Thread Pool Multithreading is a very important technical point in both java and android development. For example, each item in listview has a download function. At this time, it is unreasonable to download a new Thread every time, this will definitely cause a huge loss to memory and performance. If several threads can be enabled, when one download is complete and the other is downloaded, instead of opening the thread separ
