Function advise 

pub fn advise(
    config: &Config,
    memory_max: Option<u64>,
    history: &History,
    window: Window,
) -> Sizing

The advice for every profile of config from history, against the slice’s memory_max as config’s admission policy budgets it. Peaks, and the memory advice, go by each job’s sizing window over the history’s last 30 days (memory, ADR 0070); window.since narrows only the waits, the busy share and the starts.
