Initial support for global safepoints kept it simple by entering a safepoint for each of them one after another. This means time-to-global-safepoint is the sum of all time-to-safepoint operations. We can improve this slightly by splitting up the safepoint iteration into two operations: 1) Initiate safepoint lock (locks local_heaps_mutex_, arms the barrier and sets SafepointRequested flag for all client threads) 2) Block until all runnning client threads reach a safepoint We now perform operation 1) for all clients first and only then start with operation 2).
