Hi -
I have a relatively simple app and I've noticed significant
performance degredation over the last week. Even on extremely simple
pages like the "about" page which has the following code:
class About(webapp.RequestHandler):
def get(self):
template_values = {}
path = os.path.join(os.path.dirname(__file__), '../views/
about.html')
self.response.out.write(template.render(path,
template_values))
Yesterday, requests to this page were taking anywhere from 10-15
seconds to display from the time appengine first recorded the request
arrival - just to verify I adding some logging and it was almost the
entire time of the request before flow control was in my class.
Naturally once my code was executing it finished very quickly as all
it does is render a static html file. Some requests finished almost
instantaneously, but consistently I ran into the enormous delay. This
pattern leads me to believe that I'm being affected by the "cold
start" phenomenon but I would expect that as I continued to hit
refresh to generate logging data that all subsequent loads would be
fast, but many were not. Any insights?
