Do you know the architecture of this machine? It's extremely streamlined for data throughput (IO) at the expense of computational ability. In particular: - it runs at a relatively small clock speed (1 GHz - 1.4 GHz) - it's terrible for floating-point calculations because there is only one FPU shared by all 32 logical processors While it will be screamingly fast for serving static content, and pretty decent for light database jobs, this not an optimal platform for dynamic web applications, especially for Python since the language's so dynamic and it doesn't support SMP. Since it's so optimized for a certain purpose, you can freely consider it a special-purpose machine, rather than a general-purpose one. Even if you manage to get Zope to spawn parallel request handlers (probably via something like fastcgi), if the web application is CPU-intensive you won't be happy with its performance (for CPU-intensive tasks you probably don't want to spawn more than 8 handlers, since that's the number of physical cores in the CPU).
