I'm not sure multi-threading is the issue you think. Threads is, but only for architectural reasons. Using multiple processes to complete a task seems very sensible to me. Yeh, sorting is isolated enough to try out some of those ideas on. I was unaware of the work on finding medians, so thats a good way of dividing the workloads for parallelism. -- Simon Riggs 2ndQuadrant http://www.2ndQuadrant.com ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
