I understand the preference from an esthetics point of view. From a quantitative performance point of view, in an environment where you want to minimize the activity that is running on a lightweight cluster node, it has been shown that 1 is better than 2. So, all other things being equal, if we can have 1 daemon with TCP sockets instead of a daemon with unix domain sockets and a daemon that turns that into TCP sockets, on a reasonably large cluster (1024 or more nodes) you're much better off with 1 daemon. 1024 node clusters are not uncommon these days. Again, this is not an issue of esthetics, it's an issue of measured performance. ron ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.
