confluence不支持群集，是因为hibernate吗？

Clustering
Confluence does not currently support deployment in a cluster. If you deploy Confluence in a clustered environment, you should set up server affinity so that it is only deployed on a single server in the cluster.

The reason for this is that Confluence was initially designed to scale vertically on a single machine, and makes a number of compromises concerning use of in-memory caches and disk access that do not translate into a clustered environment. Work is underway to produce a clusterable Confluence (under the code-name 'Massive'), but we do not currently have a firm delivery date.

For the time being, it may be necessary to deploy multiple Confluence servers, dividing your departments or projects amongst the servers so that the data and load are shared between them. Once Massive is a reality, we will provide tools to combine these back into a single deployment.

不过对于巨大访问量的web应用来说，性能解决之道还是在于动态页面静态化和页面缓存上。所以这个时候你用Java也好，PHP也好，Hibernate也好，iBATIS也好，都无关紧要了。

经常看到大家提到动态页面静态化，典型的做法是什么呢？例如我现在已经有一个ww+freemarker/spring/hibernate做好的网站，如何对它进行部分页面（比如新闻）的静态化呢？有没有一个通用的做法？

说到群集，其实凡是JVM内部带状态的数据都需要复制，而真正最大的挑战不来自于Hibernate，而在于你采用的缓存对群集的支持程度，例如你如果使用JBossCache，就效率相当不错。当然，一些高端商业品质的缓存可以提供更好的效率。
