`Microsoft Windows 95 Resource Kit
`
`Benefits of the 32-bit file access driver over MS-DOS—based driver solutions
`include the following:
`
`rs Dramatically improved performance and real-mode disk caching software
`a N0 conventional memory used (real~mode SMARTDrive has been replaced)
`a Better multitasking when accessing information on disk
`a Dynamic cache support
`
`Both MS-DOS and WindoWs 3.1 used 16—bit real-mode code to manipulate the
`file allocation table (FAT) and to read to and write from the disk. Being able to
`manipulate the disk file system from protected mode removes or reduces the need
`to switch to real mode to write information to the disk through MS-DOS, thus
`resulting in a performance gain for file I/O access.
`
`The 32-bit VFAT works with a 32-bit, protected-mode cache driver (VCACHE).
`This driver replaces the 16—bit, real-mode SMARTDrive disk cache software
`provided with MS-DOS and Windows 3.1. The VCACHE driver features better
`caching algorithms than SMARTDn've, to cache information read from or
`written to a disk drive. The VCACHE driver also manages the cache pool for the
`CD-ROM File System (CDFS) and the 32-bit network redirectors provided with
`Windows 95.
`
`Another big improvement in VCACHE over SMARTDrive is that the memory pool
`used for the cache is dynamic and is based on the amount of available free system
`memory. Users no longer need to allocate a block of memory as a disk cache. The
`system automatically allocates or deallocates memory used for the cache based
`on system use.
`
`For example, as you perform a large number of activities on the network,
`Windows 95 increases the size of the cache. As network activity decreases
`and more applications are started, Windows 95 decreases the cache size.
`
`CD-ROM File System
`The 32-bit, protected—mode CDFS implemented in Windows 95 provides
`improved CD-ROM access and performance over the real—mode MSCDEX driver
`in Windows 3.1. (CDFS conforms to the ISO 9660 standard.) The CDFS driver
`cache is also dynamic, requiring no configuration or static allocation on the part
`of the user. For information about the CD—ROM cache, see Chapter 17,
`“Performance Tuning.”
