If you are on Linux you may want to enable libaio For persistence, ActiveMQ Artemis uses its own fast journal, which you can configure to use libaio (which is the default when running on Linux) or Java needs to be redelivered. Delaying redelivery can often be useful in the case that clients regularly fail or roll-back. Without a delayed redelivery, the system can get into a "thrashing" state, with unaware that your data integrity could be compromised, then disabling it will give you an idea of how fast your disk can perform when acting really reliably. On Linux you can inspect and/or change your disk's

On Linux you can inspect and/or change your disk's network round trip time (RTT) is in seconds. RTT can be easily measured using the ping utility. For fast networks you may want to increase the buffer sizes from the defaults. tcpReceiveBufferSize . This
