After set "Max Idle Instances" to 1 instead 3, no slow startup warnings in my app log. Magic!

Before the change, with "Max Idle Instances" set to 3, there is a slow
startup warning almost every 5 minutes, which make the user experience
intolerable.

Hope google will fix this bug soon. This would be a serous bug.

GAE docs says:
http://code.google.com/appengine/docs/adminconsole/performancesettings.html#Setting_the_Number_of_Idle_Instances
(... Max Idle Instances ...)
Setting a low maximum means your application costs less to run, but
may encounter more startup latency during spikes in request volume.
Setting a high maximum means that your application will cost more to
run, but will encounter less latency during spikes in request volume.

But the reality is on the contrary.

Do you really think the shotgun approach of swamping the group with lots of little 
similiar postings with either just a comment/statement and sometimes a question 
will get you the information you want ?

no, and I don't know why. No gae people answer my questions.
I really don't know why. I don't know if they have noticed this
problem or not.
And I don't know if they have confirmed or denied this problem.
But the problem is really there, this problem makes my website
visitors very unhappy.
What should I do, do you think?

Have you bothered to search or look through the message groups for the last month?  A lot of the questions about how the scheduler works and the impact of Max / Min idle instances have been answered many times.

As Tim said, swamping the message board with many unconstructive messages will just mean that you get no responses.

yes, I do.
The instance scheduler doesn't the what as the gae docs or faqs says.
That is why I post my threads.

Which one is unconstructive?
