Improving application responsiveness with the BFQ disk I/O scheduler
Paolo Valente, Mauro Andreolini · 2012
BFQ (Budget Fair Queueing) is a production-quality, proportional-share disk scheduler with a relatively large user base. Part of its success is due to a set of simple heuristics that we added to the original algorithm about one year ago. These heuristics are the main focus of this paper.
