Testing Scalability using Japex
By pelegri on Feb 10, 2006
New architectures like UltraSPARC T1 deliver many usable threads in a very small power/space envelope. This means that horizontal scaling of applications becomes very important and so is the ability to easily test software scalability. Santiago describes to use Japex to quickly Test Scalability by running a number of tests varying the number of software threads and the number of hardware cores (he used a SunFire T2000 with Solaris).
