• Binary emulator for OpenBSD applications. Emulator sits on top of ExOS library.

• XCP---use DMA to copy data into and out of buffer cache without involving the CPU.

• Cheetah HTTP/1.0 Server---use extensible I/O library

  • transmit data directly from file cache

  • delay ACKing HTTP requests (piggyback on response)

  • HTML-based File Grouping (lots of fine tuning!)
