I'm trying to execute multiple processes instances concurrently. I`m experiencing a locking behaviour. If I execute linearly 10000 process instances, it takes an average 0.4 ms. If I execute concurrently (in 10 threads) 1000 process instances, it takes from 1.5 to 25.0 ms average, depending on how loaded is the system. How can I avoid this synchronization/ concurrency locking. All my processes are thread safe, and I`m not using persistence at all.
