Yep, it's enough. Remeber, it's executor service. It has no sense to cluster
a task that will take less then 100 millis in average. So, taking 10 updates
per task, it should handle 10000s/10*0.1 = 100s parallel tasks. Its OK. It
will handle a cluster of ~20 powerfull cluster nodes. If I will have more, I
can easily have a set of independant servers with tasks distributed over

BTW: Does this number change with new servers or replication makes it worse?
