> That's why Java is used for those kind of applications

I'm not convinced that's the reason why Java is used for it. There are native alternatives like HPCC which claim to perform better.

As was noted, concurrent access to shared data is not something very common in such distributed computation scenario. Well designed processing will avoid it, and thus will avoid need for locking as well.

The goal with performance is almost never to get the maximum possible performance but the best peformance/effort ratio for your needs. This is true even for performance-critical applications. As there are diminishing returns, every increase in performance costs more than the previous. Very, very few applications are willing to invest an extra 30-50% effort to go from 98% (of maximum performance) to 100%.

As to concurrent access -- see my other comment (depends on use-case).
