These two days more busy, wrote two of JS performance defects and solutions of the article ("JS performance defects and JIT solution," "JavaScript garbage Collection Analysis"), mainly describes the problem of UNTYPED,GC and JIT engine solutions. But with respect to the JS engine, I think the DOM-led performance problem deserves more attention.I.

The concept of performance testing, I will not say, Baidu a bit, will come out a large pile, each statement has a certain truth. What is a performance test? Please do not tell me to test the performance of a Test object:), performance testing, as far as I know, many times it is difficult to locate, there are a lot of t

SQLite performance optimization instance sharing, sqlite performance optimization instance The first cache database to be found in iOS development was SQLite, which was also used as the backbone in the future. In the past, SQLite was not used to read and write large amounts of data, therefore, there is not much focus on performance optimization. This time, we hav

How does the use of inheritance, especially in the STD container, affect program performance?From my personal experience, constructor has a great influence on the creation

As I mentioned in the previous article, for full virtualization and para-virtualization, a virtual network interface that needs to be assigned to a virtual machine requires a virtual Switch vswitch (which can be used with hypervisor) to forward the packets from the virtual network interface to the physical interface. But in a complex system, the performance of this virtual switch is often not good. Open source project Netmap[1] made a high-
