 ## Introduction
 
-DCPerf is an open source benchmarking and microbenchmarking suite, originally developed by Meta, that faithfully replicates the characteristics of various general purpose data center workloads. One of the key differentiators compared to alternative benchmarking software is the fidelity of micro-architectural behavior replicated by DCPerf, for example, cache misses and branch misprediction rate.
+DCPerf is an open-source benchmarking and microbenchmarking suite originally developed by Meta. It faithfully replicates the characteristics of general-purpose data center workloads, with particular attention to microarchitectural fidelity. DCPerf stands out for accurate simulation of behaviors such as cache misses and branch mispredictions, which are details that many other benchmarking tools overlook.
 
-DCPerf generates performance data to inform procurement decisions. It can also be used for regression testing to detect changes in the environment, such as kernel and compiler changes.
