我只是在玩Snap框架,想看看它是如何针对其他框架(在完全人为的情况下)执行的。配置捕捉性能
我所发现的是,我的捕捉应用在约1500请求冠上/秒(应用程序是简单的snap init; snap build; ./dist/app/app
,即没有代码更改通过扣创建的默认应用程序。):

我然后发射了Grails应用程序,它似乎如Tomcat(一旦JVM预热)可以采取多一点的负载:

我猜,其中的一部分可能是Tomcat的似乎是事实保留大量的RAM,并可以保留/缓存一些方法。在这个实验中,Tomcat使用超过700MB或RAM,而Snap几乎没有接近70mb。
问题,我有:
- 上午我比较苹果和桔子这里?
- 采取什么措施来优化捕捉吞吐量/速度?
进一步的实验:
然后,通过mightybyte的建议,我开始与+RTS -A4M -N4
选择实验。该应用程序每秒能够提供超过2000个请求(增加约25%)。
我还删除了嵌套的模板,并从顶级tpl
文件中提供了一个与之前相同的文档。这将性能提高到每秒超过7000个请求。内存使用量上升到700MB左右。
