optimizing the concurrency of requests—that is, handling different kinds of requests inseparate pipelines—resulted in efficiencyimprovement of up to 40 percent. Furthermore, the cache hierarchy exploits the weaklyordered nature of write-combining stores toincrease the maximum number of concurrentrequests from a single Intel Architecture (IA)core from 10 to 40þ. This change greatlyincreased the streaming write bandwidth tomemory for single-thread workloads.
