[jboss-dev-forums] [Design of Messaging on JBoss (Messaging/JBoss)] - Thread usage in paging

[timfox]

I've just noticed that paging uses a new thread per address.

This isn't going to work, since we may have many thousands or tens of thousands of addresses.

Instead you could get a thread from a cached thread pool to perform the depage when PagerImpl::messageDone is called.

Also having many different PagingStores paging/depaging concurrently to the file system may provide perf problems. 

I'd really like to see some results of this performance. It might be a better to make sure only one page/or depage is done at a time (queue them for all destinations and use a single thread?), otherwise the disk head will be skipping all over the place.
