Why would more CPU cores on virtual machine slow compile times?

[edit#2] If anyone from VMWare can hit me up with a copy of VMWare Fusion, I’d be more than happy to do the same as a VirtualBox vs VMWare comparison. Somehow I suspect the VMWare hypervisor will be better tuned for hyperthreading (see my answer too)

How can I distribute a unique database already in production?

Let’s assume a successful web Spring application running on a MySQL or PostgreSQL database. The traffic is becoming so high and the amount of data is becoming so big that a distributed database solution needs to be implemented to address scalability issue.

Splitting big request in multiple small ajax requests

I am unsure regarding the scalability of the following model. I have little experience with large systems, big number of requests and so on but I’m trying to build some features considering scalability first.

Is BDD scalable for medium to large projects?
