Spring 2.5 Perfomance Improvements 200% 直逼 Guice
来源:互联网 发布:收听广播的软件 编辑:程序博客网 时间:2024/05/21 10:24
并发性能提升的原因之一是使用了 ConcurrentHashMap,原来的 Collections.synchronized(new HashMap()) 存在同步锁的性能瓶颈;
如果你是用JDK 5.0或以上的版本,就可以直接得到这个性能的提升的好处了。
或者下载 Emory concurrent utilities backport 加到 CLASSPATH 中

当然还要努力,越快越好啦。。。

The upcoming Spring Framework version 2.5 will bring a 200% improvement for concurrent access over Spring 2.0.*. I used Crazy Bob's Semi Useless Benchmark ™ as a starting point. I fiddled with the code slightly to change the default behavior from "prototype" to "singleton", and I saw that spring 2.5 was faster than Guice for singletons.
Here are some benchmarks (there is variability based on the runs)
* Spring 2.0 vs. guice 1.0:
o Prototype: Single thread: Spring is 50-150X slower. Concurrent: Spring is 50-150X slower.
o Singleton: Single thread: Spring 3X slower - 2X faster. Concurrent: Spring is 5-10X slower
* Spring 2.0.6 vs. guice 1.0:
o Prototype: Single thread: Spring is ~10X slower. Concurrent: Spring is 5X slower.
o Singleton: Single thread: Spring 2X slower - 2X faster. Concurrent: Spring:Guice ~2:3
* Spring 2.14m vs. guice 1.0:
o Prototype: Single thread: Spring is 5-7X slower. Concurrent: Spring is 3-4X slower.
o Singleton: Single thread: neck and neck. Concurrent: Spring is 1-1.5X faster
* guice 1.0:
o Prototype: Single thread vs. Concurrent: Concurrent might be a bit slower than single threaded
o Singleton: Single thread vs. Concurrent: Concurrent is quite a bit faster than single threaded
