However, the industry was hitting a thermal and physical wall. Processor clock speeds could only increase so much before physics got in the way. The solution to gaining more performance was parallelism. Instead of one 100MHz chip, why not use two 50MHz chips?
Despite these challenges, the benefits of running UNIX on modern architectures are significant. RISC and superscalar processors offer improved performance, increased scalability, and enhanced reliability. These benefits have made UNIX an attractive choice for a wide range of applications, from scientific simulations and engineering workstations to servers and data centers. unix systems for modern architectures -1994- pdf
: Some critics point out that the book lacks coverage of NUMA (Non-Uniform Memory Access) and the specific interactions between caches and networking or storage subsystems. Access and Availability However, the industry was hitting a thermal and
