MICHECK A0a Copyright (c) 2000 Allegro Consultants, Inc. This program reports if the Measurement Interface (MI) is on or off. When the MI is on, your CPU performance degrages by 5% to 25% (in *rare* cases, even more). This is easy to demontrate: 1) ensure MI is off 2) enter: :FILE NULL=$NULL 3) time: :FCOPY FROM=NL.PUB.SYS;to=*NULL (hit return when asked if the record size is ok) 4) time: :FCOPY FROM=NL.PUB.SYS;to=*NULL (we do it a second time to avoid questions about how much of the file was in memory) 5) turn on MI 6) time: :FCOPY FROM=NL.PUB.SYS;to=*NULL 7) time: :FCOPY FROM=NL.PUB.SYS;to=*NULL (we do it a second time to avoid questions about how much of the file was in memory) Compare the times from steps 4 and 7!
