title: ShenYu Optimize keywords: [“Optimize”] description: performance optimization for Apache ShenYu
Description
- This doc shows how to do performance optimization for Apache ShenYu.
Time Consumption
- Apache ShenYu is JVM driven and processing time for a single request is nearly between
1-3
ms.
Netty Optimization
spring-webflux
is one of dependencies of ShenYu, and it uses Netty in lower layer.- The demo down below demonstrates tuning ShenYu by customizing params in Netty.
@Bean
public NettyReactiveWebServerFactory nettyReactiveWebServerFactory() {
NettyReactiveWebServerFactory webServerFactory = new NettyReactiveWebServerFactory();
webServerFactory.addServerCustomizers(new EventLoopNettyCustomizer());
return webServerFactory;
}
private static class EventLoopNettyCustomizer implements NettyServerCustomizer {
@Override
public HttpServer apply(final HttpServer httpServer) {
return httpServer
.tcpConfiguration(tcpServer -> tcpServer
.runOn(LoopResources.create("shenyu-netty", 1, DEFAULT_IO_WORKER_COUNT, true), false)
.selectorOption(ChannelOption.SO_REUSEADDR, true)
.selectorOption(ChannelOption.ALLOCATOR, PooledByteBufAllocator.DEFAULT)
.option(ChannelOption.TCP_NODELAY, true)
.option(ChannelOption.ALLOCATOR, PooledByteBufAllocator.DEFAULT));
}
}
- The
shenyu-bootstrap
module offers this class, you may modify it when benchmarking your app if necessary. - You can get references of business thread model from thread model
