Java latency instance analysis: Lock vs Synchronized

Java latency instance analysis: Lock vs Synchronized

This article discusses through examples:

-Java. concurrent. Lock: Garbage created
-Compare Lock and synchronized
-How to calculate latency through programming
-Impact of Lock and synchronized Competition
-The possible impact of co-ordinated omission missing in the latency test on the result

Go back to one of my favorite themes: Create and allocate garbage. Can be obtained from my previous articles, such as the primary rule of performance optimization and the primary rule of Performance Optimization: Escape analysis results)
