)Go language is essentially a static language, with slightly lower development efficiency, but stronger performance and more suitable for the development of underlying softwareSwoole uses PHP language and dynamic scripts Language, the best development efficiency, more suitable for the development of application software
IO model
go language uses a single-threaded eventloop to process IO events, and multi-threads implement coroutine scheduling. Execute user-level codeswoole uses multi-threaded eventloop to process IO events, and multi-process executes user-level php code
Go's processing of IO events is single-threaded and cannot take advantage of multi-core, throughput Slightly weaker than swooleIn the actual TCP/UDP intensive IO stress test, swoole performed slightly better than goGo coroutine (goroutine) runs on multiple threads, and threads It can share stacks and file descriptors, has more powerful functions, and has more advantages in implementing connection pools and concurrency libraries. An additional problem is that there is a data synchronization problem, and users need to consider locking themselves. Swoole's user code runs in a multi-process environment, without locking issues to consider. But there is no direct access to memory and resources. It is necessary to use the Task process to achieve transfer.Language performance
Go language is statically compiled, the performance of the language itself greatly exceeds that of PHP, and intensive computing has more advantagesphp is dynamically interpreted The language performance is poor and not suitable for intensive calculation programs
Using C extensions to implement intensive calculation and large-scale call codes can solve some PHP performance problemsThe above is the detailed content of The difference between golang and swoole. For more information, please follow other related articles on the PHP Chinese website!
