from http://www.theregister.co.uk/content/4/24658.html One of the important changes in Solaris 9 is a change in the threading library. Solaris 8 had an alternate threading library that Sun was allowing customers to play around with, and this is now the default threading library with Solaris 9. The replaced threading library will not affect application compatibility - Solaris 8 apps will run unchanged - but this change in threading schemes will allow nearly all applications to scale to larger processor counts than they currently can on Solaris 8 servers. (This is known as vertical scaling in the nomenclature of the server business.) no idea what this will do for Zope... -- Anthony Baxter <anthony@interlink.com.au> It's never too late to have a happy childhood.
