When you have thousands of automated tests in a Continuous Integration environment, time to perform test execution can be a problem. XStudio already provided a good tooling to fix that issue as you were able to execute your tests remotely on several remote computers (and even on several independent threads on each agent).
The step further has be reached in XStudio 1.7: you can now specify a pool of agents and the system will pick the first available agent in the pool.
This way you can efficiently "load-balance" your test executions.
Hope you will enjoy it!
