Slightly related to this... Somehow if I were to guess, Zope could definitely handle the traffic of a big media site, supposing there was at least one or more of the following: 1 - use of ZEO 2 - #1 plus heavy use of front-end caching and proxy-based load-balancing of ZEO nodes w/ Squid 3 - (most aggressive) Load-balance several boxes doing #2 using L4 switch #3 is in theory, the smartest move if you want to support daily 8-digit hit-counts, if the same "semi-dynamic" content (of which news is), only has to be generated once, then cached, it would be served out of RAM as an in-transit object from the proxy server. This caching arrangement (well, for now, 1&2, with 2 ZEO client boxes and a ZSS) seems to work well for our online classified ads site, which sustains around a million plus hits on a good day. Most of those hits, the ZEO clients / Zope servers never see because most are images, which are cached in Squid on the first load. I'm pretty sure that with enough hardware (i.e. 1, 2, and 3 above) this same sort of arrangement could scale just fine to 8-digit page views per day for a news site, supposing you have the bandwidth to accommodate that sort of traffic as well.

BTW, has anyone got information about the way the cbsnewyork website kept (or didn't keep) running during the information rush after the crash ? It would be a benefit for the whole Zope community to know if Zope is stable to endure such a trafic rush ! Many thanks, P.-J.

As is known by many here, cbsnewyork is a Zope site and is up and servicing NYC with information during these days of infamy.
