The collected data is fed into a performance model which estimates how fast the simulation would run on a system with enough host cores and Simics Accelerator licenses to allow each cell to run on a dedicated core. The performance model also gives some insights into the performance implications of various min-latency settings (settable though the set-min-latency commands).
The interval parameter should normally be set to a value of the some order as the min-latency setting of interest.
