Benchmark

The benchmark application measures latency, throughput, and memory usage of all oveRTOS abstractions. Results are printed as formatted ASCII tables via OVE_LOG.

What it measures

Suite	Metrics
Thread	Creation latency, context switch time, yield overhead
Queue	Send/receive latency, throughput (messages/sec), full-queue behavior
Mutex	Lock/unlock latency, contention overhead
Timer	Start latency, callback jitter, periodic accuracy
Memory	Heap usage (total, used, free), allocation throughput
Stream	Write/read throughput (bytes/sec), trigger latency
Workqueue	Schedule latency, deferred execution overhead
Event Group	Set/wait latency, multi-bit pattern matching

Each suite runs configurable iterations (default 1000) and reports min/max/avg/median statistics.
