Abstract: The purpose of this paper is to report results of simulations of two algorithms for free space collection in log-structured storage systems. The algorithms considered are the age-threshold algorithm of Menon and Stockmeyer and the fitness algorithm of Butterworth. The simulations were done using a trace collected by Ruemmler and Wilkes from a file system over a period of two months. The performance of an algorithm is measured by the amount of disk I/O done as a result of free space collection.... (Update)
