Limits: Concurrent Macro Execution Latency in Minitab Server

Goal

Determine how Minitab Server handles simultaneous macro submissions and whether a documented limit or performance degradation exists when multiple users trigger macros at the same time.

Constraints

Minitab’s macro interpreter runs on a single thread and queues jobs regardless of how they are launched. Observed latency scales with concurrent submissions, but the documentation does not explicitly state a concurrent‑execution limit or offer configuration options.

Unresolved Questions

• Does Minitab Server guarantee isolation between concurrent macro jobs, or are they processed in a strict FIFO queue that can lead to cumulative delays?
• Is there a documented maximum number of concurrent macro executions before latency becomes significant, and has this threshold changed between Minitab 20.x and 21.x?
• Are there any server‑side settings or macro‑level flags that enable parallel macro processing or thread pooling, or is single‑threaded execution the only supported model?
