Wow, I don't know what to say, how about I cc this email to a few people to see
how long does it take load this dataset.
Tom, jeff and Don, can you give it a try and let us know the time it takes to
load this dataset in the IDV? I cannot believe there is this much difference
between IDV and McV.
Thanks,
