Google App Engine - how many quotas does one datastore use?

Question

The latency for the data warehouse is about 150 ms - http://code.google.com/status/appengine/detail/datastore/2010/03/11#ae-trust-detail-datastore-put-latency .

About how much CPUTime is used by a single data warehouse with a data size of 100 bytes, in an object that has only 1 property, and not indexes?

Also, does anyone know how much extra overhead in CPUTime this data warehouse does through the task queue?

I plan to do some testing with this later to figure it out, but if anyone already knows what will help me :).

Note. This relates to the following question: Google App Engine - How Reliable are Logs? .

Answer 1

As the poster said in a comment, one place for a data warehouse takes about 75 ms of processor time and about the same wait time.
