I have a somewhat different question about ZServer performance vs. Apache/pcgi. Under 1.10.3, it seems that clients can bog down or even bring down the Zope server (the deprecated old one, not ZServer). A client with a slow connection will hold the server's attention until they've managed to load a whole page, and if you break the connection (by pushing Stop or clicking a link on a partially loaded page) the server dies of a broken pipe. Apache/pcgi improves reliability hugely, by locally buffering Zope's output and shielding it from connection issues. I realize that ZServer is *far* more robust, with it's threaded Medusa base, but is it as completely free of connection-related problems as an Apache/pcgi/ZServer setup? Evan "4am" Simpson
