The "Top" designation refers to the high-performance, multi-threaded, high-availability configuration of this server. It is designed for environments where latency cannot be tolerated—such as high-frequency simulation clusters or large design teams working on assemblies with 10,000+ parts. solidsquad universal license server top

Phase 1: Preparation
