- OpenHFT provides solutions for improving Java data locality and inter-process communication (IPC) transport, enabling ultra-low latency real-time Java deployments. - It includes Chronicle Map, an off-heap concurrent map that avoids garbage collection pauses compared to on-heap maps. It also provides faster IPC than UDP/TCP via shared memory. - Tests show Chronicle Map accessed via shared memory IPC can be over 1000x faster than Red Hat Infinispan accessed via UDP for a distributed cache workload.
