Struct ReadSparseCold

Source

pub struct ReadSparseCold { /* private fields */ }

Expand description

A benchmark that measures how long pread calls take to a sparse file that should not already be cached in memory. The file’s sparseness is designed to defeat the gains of readahead without making an extremely large file, but will also result in testing access to many small extents.
