Start interval
5 min
Memory per job
256 MiB

Expected results

Maximum overlapping jobs
4 jobs
Peak job memory
1024 MiB

How to use this tool

  1. Enter execution runtime, start interval, memory per job in the displayed units.
  2. Calculate the scenario, then compare it with measurements before changing a system.

Try this example

{
  "run": 17,
  "period": 5,
  "mem": 256
}

Accuracy and scope

Fixed runtime and exact periodic starts; no locking, queues or schedule jitter.
