Introduction
Windows 95 does not provide any native support for monitoring the performance of VxD services. VxDMon is a system monitoring tool that allows you to profile Windows 95 VxD performance and behavior. VxDMon‘s functionality is built on VxD service hooking. By using service hooking, VxDMon is able to monitor and time, via the Pentium‘s rdtsc (ReaD Time Stamp Counter) instruction, any and all VxD services including those of VxDs built into Windows and those added by a developer. In addition, VxDMon keeps track of VxD service call histories so that it can display useful information such as the list of all services that were called by a particular service during a monitoring session. This combination of VxD performance and call history information provides a never-before-seen look into the behavior of Windows.
Installation and Use
VxDMon was designed for Pentium processors and requires that VXDMON.EXE be in the same directory as VXDMON.VXD. It will run on a 386 or 486 proce
