Instance spinning for a user facing request - Standard Java Appengine

[Rajesh Gupta]

Dear Team,

I am experiencing the instance spinning for a user facing request on a low traffic test website.

I have the following in the appengine-web.xml

    <instance-class>F1</instance-class>

<automatic-scaling>

   <min-idle-instances>1</min-idle-instances>

   <max-pending-latency>10s</max-pending-latency>

</automatic-scaling>

Please help.

- I suggest you first investigate your requests using Stackdriver Trace to find out where the latency is occurring (as it is often code related). 

- If the latency is seen before any code execution, you should then check to see how many dynamic instances were running during these requests using the App Engine dashboard 'instances' graph. 

- If there were no dynamic instances, or if they were busy (which can be seen under the 'Utilization' and 'Memory Usage' graphs) than this would explain the latency as your requests were waiting for a free instance. 

After your research if you determine that this isn't an issue with your code or your scaling configuration, and is an issue on App Engine, you can open a Public Issue Tracker to properly report it. Just ensure you provide more details about these specific requests.
