1-2 days ago startup time increase from 1-3 second to 10-30 seconds with same code.

I use python 2.7 multithreading.

Code in this request read one value from memcache and return it to user. If memcache empty it read and render simple html-template from template in local filesystem. Both use equal cpu_ms.

Same code work fine in test application. Startup time in test application about 1-2 second.

I send production issue yesterday in night, but don’t receive answer.

I try change instance type from F1 to F4, startup time for F4 8-10 seconds.

AppID of my app: f1f2ru

    I don’t know reason of first increase startup time.

    Problem of increase operations time is my mistake:
    my application do query:
    object.date < datetime.datetime.now()

    and my datastore have no objects with date < datetime.now(), but it have objects with date = None (null). I forget about null it is normal, indexed value and null < any value.
