Existing research suggests that a considerable fraction (5-10%) of the source code of large-scale computer programs is duplicate code (“clones”). Detection and removal of such clones promises decreased software maintenance costs of possibly the same magnitude. Previous work was limited to detection of either nearmisses differing only in single lexems, or(More)
Web cache servers (proxies) are increasingly popular for reducing Internet traac and improving response time. The disk subsystem appears to be a bottleneck in such servers. We present techniques for improving disk performance of Web proxies and evaluate them with simulation. The disk workload of proxies has a signiicant volume of new le writes. We show that(More)
