Hello Vinni, Thank you for the quick reply.
I did install appstats and try to find out if there were the bottle necks. The chart was basically reading from the datastore and then there was a 5 seconds without any "information". Now it behaves different because it reads all from memcache (as you will see, there is no big improvement). I am going to make an screenshot without the memcache, it will take some time. I also measured the time (using time.time( )) between different moments of the answer. Here is the log: 22:31:54.677 GETTING KEYS 0.182710 22:31:58.785 GETTING TRIPS 4.290660 22:31:58.785 FILTERING 0.000270 22:31:58.794 GETtING TA PROFILE 0.008220 22:32:04.771 COMPOSING ANSWER 5.977440 22:32:04.854 GETTING RATES 0.083230 If there is any other information you can consider useful just let me know. <https://lh3.googleusercontent.com/-tP-3QzK6AYI/U2auD4TlV4I/AAAAAAAAEmE/Z7K3TzmZhtk/s1600/appstats.png> -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
