You're thinking of the *DAQ* version. The current version of NI-VISA
is 3.0.1 on the Windows platforms. The version that came with LabVIEW
6.1 was NI-VISA 2.6.

It looks like the others have given you some good ideas and
explanations. The is only one thing that comes to mind.
Have you compared the VISA versions?
The were some performance enhancements implemented in one of the VISA
updates.

The VISA versions are the same, 6.9.3 but I was going to update it to
the latest 7.1. I forgot to mention that this machine used to run NT
but the hard drive crashed so I had to replace it. I was having a hard
time replacing the NT so in a crunch loaded Win98. If the customer can
get some down
I wouldn't expect a speed difference because of the serial port. What
about the performance of the different PCs? I suspect the Win-NT is
more powerful. If so, it may be capable of doing the other tasks
(non-serial communication) faster.
One bottleneck may be writing data to the HardDrive.
Having run LabVIEW on a variety of systems, I've found that it's not
that unusual to find a program run faster on an NT system than on
other systems. I haven't compared WIN2000 with NT yet, but WIN2000
does run faster than on XP.
NT has *MUCH* better multitasking than Win98, so this explains
