MacFS: A Portable Macintosh File System Library
Peter A. Dinda, George C. Necula, Morgan Price
We describe the Macintosh Hierarchical File System and our implementation and note that the design is not well suited to reentrancy and that its complex data structures can lead to slow implementations in multiprogrammed environments. Performance measurements show that our implementation is faster than the native Macintosh implementation at creating, deleting, reading and writing files with small request sizes, but slower than the Berkeley Fast File System (FFS.) However, the native Macintosh implementation can perform large read and write operations faster that either our implementation or FFS.
