Is this just a statement, or are you asking for help?

I will assume you asking for advice.

Appengine start up times is something your can't ignore.

Do some profiling and see what is going on.  Try to do things lazily.

If you are asking for help I would suggest you mention if your using java or python and what frameworks

my app is a simple Hello World JSP page, not use any framework.
first visit, about 5s. second and after, about 1s.
if add several times db access, about 8s.

I'm using gaelyk for GAE-J. http://gaelyk.appspot.com/

coldstart is about 6-8 sec. after that, it's very fast.

one of the reasons always-on instance was a very welcome change for
the java side of the GAE community :)

about web application, it will stop if long time not visit.
when someone visits it will start again.
i think its startup is very slow.

Sounds like you're using RPCs serially, which will often lead to poor
performance.  Profile your app with Appstats:
  http://code.google.com/appengine/docs/java/tools/appstats.html

then try to batch any operations you can.

I think Java typically has long startup times, but I've got no idea
what is 'normal' for Java.

the short answer is, pay $9/month to have 3 always on instances :)

Is this what happens when you accidentally use YouTube instead of Google Translate to compose your email?
