There are more roads under the sun that lead to enlightenment: http://www.kegel.com/c10k.html Multi-threading is *not* the holy grail of high-performance IO. My current thinking is that we want to max out the sql-server by serving many clients from a single (or a few) server processes that together share a single pool of sql-connections. Currently the maximum number of concurrent clients is limited by the maximum number of concurrent connections allowed by the sql-server, even though many of those sql-connections will be idle most of the time. Making the server code multi-threaded is no remedy here (afaik). But using multiplexing IO is. After that, the raw performance of the sql-server will become the main performance bottleneck (I suspect). As well it should be. Don't expect this stuff until the 2.3 development series though. 2.1 is mainly aimed at adding new features, improving imap performance and doing code cleanups. -- ________________________________________________________________ Paul Stevens paul at nfg.nl NET FACILITIES GROUP GPG/PGP: 1024D/11F8CD31 The Netherlands________________________________http://www.nfg.nl
