You say your DB is 95% read only, but you can't cache. I assume you mean you can't cache entirely rendered HTML pages with something like squid. But you *can* and should cache the database from the database with something like Cache::Memcached. I'd normally suggest Cache::FastMmap, but you've already indicated you're growing enough to need to be able to scale across multiple machines. I think Ask Bjørn Hansen's presentation covers all of the recent generally accepted wisdom: http://develooper.com/talks/Real-World-Scalability-Web-Builder-2006.pdf --------------------------------- Frank Wiles <[EMAIL PROTECTED]> http://www.wiles.org ---------------------------------
