Measures different parts of the slot confirmation processing pipeline.

Fields

started: Instant

Moment when the ConfirmationTiming instance was created. Used to track the total wall clock time from the moment the first shard for the slot is received and to the moment the slot is complete.

confirmation_elapsed: u64

Wall clock time used by the slot confirmation code, including PoH/signature verification, and replay. As replay can run in parallel with the verification, this value can not be recovered from the replay_elapsed and or {poh,transaction}_verify_elapsed. This includes failed cases, when confirm_slot_entries exist with an error. In microseconds. When unified scheduler is enabled, replay excludes the transaction execution, only accounting for task creation and submission to the scheduler.

replay_elapsed: u64

Wall clock time used by the entry replay code. Does not include the PoH or the transaction signature/precompiles verification, but can overlap with the PoH and signature verification. In microseconds. When unified scheduler is enabled, replay excludes the transaction execution, only accounting for task creation and submission to the scheduler.

poh_verify_elapsed: u64

Wall clock times, used for the PoH verification of entries. In microseconds.

transaction_verify_elapsed: u64

Wall clock time, used for the signature verification as well as precompiles verification. In microseconds.

fetch_elapsed: u64

Wall clock time spent loading data sets (and entries) from the blockstore. This does not include the case when the blockstore load failed. In microseconds.

fetch_fail_elapsed: u64

Same as fetch_elapsed above, but for the case when the blockstore load fails. In microseconds.

batch_execute: BatchExecutionTiming

batch_execute() measurements.
