Hi Marzia, thanks for responding.  I've read that a few times actually
and it's part of what is confusing.  See:

1.
Re: http://code.google.com/appengine/kb/general.html#highcpu
That link describes a message that says:
  "This request used a high amount of CPU, and was roughly
  X times over the average request CPU limit.
  High CPU requests have a small quota, and if you exceed
  this quota, your app will be temporarily disabled."

However I get the orange/red text in my req log with yellow ! icon
saying (on mouseover):
  "This request used a high amount of CPU and may soon exceed its
quota"

I've never seen the one from the docs.  Is this the same message & the
docs are out of date, or is this a different message with a different
meaning?


2.
Also, the other issue: if a single Datastore put (an update) of a
modestly sized (<10 fields) entity is often taking ~1000ms-CPU
(=1sec), I understand that doesn't count toward runtime CPU quota
(right?), but it DOES count toward overall CPU Time used.

So 3600 puts would take a ~CPU-hour, which costs $0.10 at the proposed
rates.  That's ~$0.027 / 1000 hits, assuming a page writes just one
entity (eg counter/timestamp/etc).

It seems like (social/consumer-oriented) apps on GAE would need dozens
of ads just to break even to support the basic DS operational costs,
not even including any other costs (bandwidth, additional CPU use for
preparing/rendering pages, etc.).

Tell me my math is wrong, or that DS puts are going to be optimized
soon?
I'm just having a hard time seeing how writing a single entity takes
so much CPU.

Thank you.
