VRf-CPU Usage Question

Question asked by VRFuser on Jul 7, 1998
Members of the VRf,

Along the same lines as Mr. Timian's question: is this problem going to be
addressed, and, if so, when?  I am asking because the whole question of CPU
usage came from work I am doing for a customer at one of the National
Laboratories, and he has a real dislike for anything that looks like a CPU
hog.  As a check, we fired up LabVIEW 5 (I hope that that isn't a forbidden
word in this forum) and set up the same small program - a simple counting
loop with a delay timer in it.  When we ran this virtual instrument we found
that during the delay period, CPU usage was less then 1% as opposed to 100%
for HP-VEE 5.

My customer is now looking through his National Instruments catalogs, if you
catch my drift.  Any insight into HP's plans would be most helpful.

Greg,
Is there anything we can do as users to "prod" them along also.
