Startup Doubler 2.1 is now available. According to its developer, Marc Moini, this shareware application "...compensates for sub-optimal disk performance to make extensions, control panel, the Finder and startup applications load faster."

It is claimed Startup Doubler makes start-ups up to 50 per cent faster, the package runs on Mac OS 7.0 to Mac OS 8.6, and also supports multiple extension sets.

The cost is $20 to register a version, but try before you buy with a fifteen-day trial period. Also, available from Moini are Smart Scroll, Custom Menus and Clean-Install Assistant.
