Calculate batch processing time
Batch jobs can look small until throughput, workers and buffers are considered together. Enter item count, items per second and worker count to estimate runtime. It is useful for queues, imports, image jobs, data cleanup, email batches and background workers.
Runtime estimate
Use real throughput numbers when available and include a buffer for slow tasks.
Frequently asked questions
What counts as a worker?
A worker is one process, thread or job runner that can process items in parallel.
Why add a buffer?
Network waits, locks and retries often make real jobs slower than ideal throughput.
Can this model uneven job sizes?
No. It assumes average processing time across the batch.
