A comparison of Windows driver model latency performance on Windows NT and Windows 98

This work compares the performance of Windows 98 and Windows NT 4.0 under load from office, multimedia and engineering applications on a personal computer (PC) of modest power that is free of legacy hardware and concludes that for real-time applications a driver on Windows NT4.0 that uses high, real- time priority threads receives an order of magnitude better service than a similar WDM driver onWindows 98 that uses Deferred Procedure Calls.
