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,
Yuan
