We're looking at CMS alternatives for a very large scale content management system. Initial estimates are 850M+ documents and perhaps 1-2,000 concurrent users. I'd appreciate any pointers the community has to 1) largest production Alfresco installations you're aware of, and 2) any benchmarking information available.
Old (Unisys) benchmarks point to ability to maintain 100M documents quite easily - but don't address access times or concurrent user scalability. Anything more up to date would be appreciated.
Regards,
