Hi Jeff,

You touched a sore point. App engine forums are in filled  the questions as yours.
I can not know clear answer now.

1. I'm not sure you saw Ethan's and my posts from the past day or so about GDS on the mtt-devel list; it just occurred to me that I don't know if you're members of the list or not.  We've posted a few questions and comments that you may not have received if you're not on the list:

2. I'm still looking into the perl syntax error that caused my Big Submit to GDS to fail.  But looking at the Google logs, it looks like at least *some* of my test run results made it up to GDS.  There was a BIG spike in CPU usage (3.2 hours of CPU time!) when it submitted -- see the attached CPU usage graph from the apps dashboard.

Does anyone know why it takes so much CPU just to submit data to GDS?  3.2 CPU hours is a LOT!

It makes me a bit concerned that only part of a single Cisco MTT run submit checked through almost half of our daily CPU quota (6.5 CPU hours/day).  Is there any way to reduce the amount of CPU necessary just to submit data?
