It uses an intelligent caching system to bring the filesystem performance up to workstation levels, and far exceeds the capabilities of the standard system, Addbuffers. While any Amiga user can benefit, the greatest performance gains are realized in situtations where storage devices are important, such as compiler operation, database manipulation, manipulating large word-processng files, etc. FEATURES - Works with any AmigaDOS compatible storage device, including but not limited to: SCSI Hard Drives IDE Hard Drive (AT and XT style) ST-506 Hard Drives Trackdisk-based floppies CD-ROM drives (CDTV included!) SCSI Tape Backup Units - HyperCache employs a pre-fetch technique that intelligently reads data BEFORE IT IS REQUESTED. In this way, even first time reads that are not in the cache are accelerated. - Any number of devices, and any number of units per device (up to available memory) may be cached. Drives may be spread across multiple devices (SCSI, IDE, and Trackdisk caches resident in the same machine simultaneously). - Works with any filesystem, independant of device geometry. Alternate systems, such as MessyDOS and most CD-ROM filesystems are supported. - User-configurable cache parameters. The cache is maintained as an n-way associative line cache, where the number of lines, line size, prefetch size, and overall cache size are configurable independantly for each device being cached. Automatic configuration is also supplied for the novice user. REQUIREMENTS - Kickstart 1.2 or higher (fully compatible and tested with 2.X) - 1M RAM recommended (and it screams with 32 bit RAM!) - Floppy, Hard Disk, CD-ROM, and Tape supported DISKSPEED RESULTS A B C D 512 Byte Transfers 18395 111879 112159 477926 4096 Byte Transfers 84644 440142 553855 1510893 32768 Byte Transfers 132297 612320 565127 2112818 A - A500, Addbuffers 1024 B - A500, HyperCache Installed, auto-configured C - A3000, Addbuffers 1024 D - A3000, HyperCache Installed, auto-configured AVAILABILITY HyperCache is currently available only directly from the author, Silicon Prairie Software, for the price of $29.95 US funds.
