A couple of years ago I talked with a VEE developer and at that time such
tasks as doing an FFT with VEE was significantly slower (by a factor of ten
or so). Instrument communication is limited by the GPIB bus so there's little
difference if you use HP's VISA library or NI's. The last benchmark on program
development that I saw was a study paid for by HP and very biased in my opinion.
Also, benchmarks are only a small part of the story. Except for Agilent instruments,
you won't find many native VEE instrument drivers. A lot more manufacturers
of data acquisition cards supply drivers for LabVIEW. VEE doesn't have the
variety of toolkits that LabVIEW does. If you ever need to do database interface,
SPC, vision, motion control, sound/vibration analysis, or internet c
onnectivity,
you'll find that the VEE either doesn't have the tools or that they're not
as mature. A LabVIEW program is portable across Windows, Mac, Sun, and HP
Unix. There's also an embedded, real-time version of LabVIEW. Lastly, look
at the user community for LabVIEW. There's this forum, the info-labview mail
server, and the hundreds of Alliance members across the globe doing LabVIEW
consulting.
