Per-worker time and how much of the machine the run reached.

Fields

version: u16

logical_cpus: u64

scanner_threads: u64

wall_ns: u64

process_cpu_ns: u64

achieved_speedup_milli: u64

process_cpu_ns / wall_ns in thousandths: the speedup actually achieved.

parallel_efficiency_ppm: u64

Achieved speedup over logical CPUs, in parts per million.

speedup_ceiling_milli: u64

Amdahl ceiling implied by the measured serial share, in thousandths.

worker_count: u64

active_worker_count: u64

instrumented_busy_ns: u64

Summed outermost-span time across workers.

instrumented_blocked_ns: u64

Summed outermost blocked-wait time across workers.

worker_capacity_ns: u64

wall_ns * worker_count: the time the pool could have spent working.

idle_ns: u64

idle_share_ppm: u64

busiest_busy_ns: u64

median_busy_ns: u64

imbalance_ppm: u64

Busiest minus median over busiest, in parts per million.

busy_off_cpu_ns: u64

Time inside outermost spans that was not on CPU. Threads sitting in an instrumented region while runnable-but-not-running show up here, which is where a large worker pool loses its speedup without ever going idle.

source_blocked_ns: u64

scanner_blocked_ns: u64

queues: Vec<QueueDepthV2>
