| The size of the timed buffer on AIO. The default value is 128MiB. | Really? ;) Also, there's not mention on tuning the timeout or buffer size, and there's no explanation on what any of these things do :( Also | If this is set to true, the internal buffers are flushed right away when a transaction arrives. | JBoss Messaging was made to scale up to hundreds of producers. We try to use most of the hardware resources by scheduling multiple writes and scheduling multiple writes in a single OS call. | However in some use cases it may be better to not wait any data and just flush and write to the OS right away. For example if you have a single producer writing small transactions. On this case it would be better to aways flush-on-sync. | Is not true. This is nothing to do with transactions, flush on sync is also used in non transactional situations, depending on the sync settings.
