how does the Windows native client handle lots of file-upload tasks?

[zooko]

Fabrice, the entrepeneur behind Allmydata, says that our reference test should be 25,000 files and 100 GB -- "VERY WELL and RELIABLY!". He says this is necessary to be competitive with Carbonite, Mozy, etc.. He promises to raise the bar to 100,000 files and 500 GB as soon as we reach 25,000 files and 100 GB. ;-)

This ticket is to implement automated measurements of the performance of the Windows native client, connecting to a local Tahoe node, which is using a standard allmydata.com grid.
