Description
===========
Performance Monitoring/2 (=Perfmon/2) is a tool to monitor software.
For example it shows the percentage of FPU-instructions executed on
your processor. It uses special CPU-registers introduced by intel(TM)
with the Pentium.
System requirements
===================
- OS/2 Warp 3.0 (*UNTESTED*) and Warp 4.0
- intel Pentium or higher or
Cyrix 6x86MX or higher (*UNTESTED*)
Installation
============
Insert a line like this to your CONFIG.SYS and reboot:
DEVICE=C:\DRIVER\PERFMON.SYS
Use
===
Start perfmon.exe and enjoy.
Here is a short description of the different modes:
- Flop Execution:
Measures the ammount (in percent) of FPU-instructions executed.
- V-Pipe Execution:
Measures the ammount (in percent) of instructions executed on the
V-Pipe. It shows how good your software is adapted to the Pentium.
- BTB-Hit:
Shows how good the Branch Prediction Unit works. It shows the
ammount of right predicted branches.
- Segment Register Loaded:
Shows how much of the executed instructions are seg.reg-load
operations.
