Why I have removed the Reclaim Thread: Reclaim should aways (even when you have a high number of files) to finish before much faster than a file could be consumed or produced. The needForFile should aways fire the Reclaim event (instead of a timer). With that you never grow the number of existent files. If you create a new file when you could reuse one from reclaim, you will have createFile competing disk resources with the appendFile, what will increase latency and harm performance while the 10M file is being created. Reusing more files will improve latency. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4164755#...
