The Supreme Court (and appellate courts) are a batch system, with high throughout but poor latency. The Supreme Court reviews 7,000-8,000 petitions for certiorari each year, rendering judgment in the merits after oral argument on about 80-100 cases per year. Each case typically has hundreds of pages of briefing, rulings below, etc., and requires reference to hundreds of additional pages of precedent and other authorities. All that is done by the nine justices, each with the assistance of four clerks.
