Performance

• Interesting comparison (but very brief!)
  • m-kernel design reduces overall performance by 10-15%
    • Some kernel functions reduced by 20%
  • Is this consitent with other results (Mach, QNX, Hurd...)
  • Is this an acceptable performance degradation?
• What about HW costs?
  • Need a special purpose bus
  • Huge engineering effort
  • Possible to do with more standard components?
