I tried to optimize the implementation to make it more > eligible for runtime optimizations, tried to make loops JIT friendly by > moving out branches where I can, minimize member access in all loops, use > final members where possible and specialize the two common cases With & > Without LiveDocs. > I will attache a patch and my benchmark results in a minute. -- This message is automatically generated by JIRA.
