Hi,
I am experiencing extremely long response times for a couple of hours now.
I am using GAE/J.
I can provide app id via email.
My app has billing enabled and is using SSL VIP.
This affects both requests with API calls and static resources like images:
Static image:
ms=2655 cpu_ms=0
Controller with API calls displaying dashboard:
ms=8430 cpu_ms=131
For a list of activities 131 cpu_ms seems like a good result, but why does
the whole request last for 8.5secs?
Other odd things that I have noticed:
- My resident / reserved instance is missing - I have only dynamic ones,
there was always a permanent instance with green shield icon.
- After disabling and reenabling the application I always get
/_ah/warmup 500 87610ms 0kb - 90 seconds to start an instance? I'm not
using Spring, it usually took about 7 secs to spin a new one.

We are starting to consider moving out of App Engine. This issue and the thing
that our users tend to hit cold instances every n requests makes it not
suitable for our need
