Performance & Benchmarks

XEMS is designed for high-concurrency environments where session stability and low latency are critical. By utilizing a native sidecar process, XEMS eliminates standard Node.js garbage collection spikes and network overhead associated with external stores like Redis.

Concurrency Audit Results

The following metrics were captured during a mission-critical stress test designed to simulate a high-load production environment with 255 simultaneous users and active token rotation.

Metric	Audit Result
Transactions	255 hits
Availability	100.00 %
Concurrent Users	255
Success Rate	1:1 (Decrypted & Rotated)

Process Reliability

Singleton Enforcement

Verified that only one XEMS sidecar process is maintained regardless of the number of server instances sharing a storage path.

Collision Protection

Zero file-lock errors or IPC timeouts were recorded throughout surge testing with 1,000+ sessions.

Zero GC Latency

Because XEMS data is stored in a native Go memory space, it is not subject to the Node.js Garbage Collector. This ensures consistent latency even as the session count grows into the tens of thousands.
