An operating system’s readahead and buffer-cache behaviors can significantly impact
application performance; most often these better performance, but occasionally they worsen it. To
avoid unintended I/O latencies, many database systems sidestep these OS features by minimizing
or eliminating application file I/O. However, network traffic measurement applications are
commonly built instead atop a high-performance file-based database: the Round Robin Database
(RRD) Tool.
