I post this to the groups because the Google App Engine Support is neither answering my questions I posted to the request form (http://code.google.com/support/bin/request.py?contact_type=AppEngineCPURequest) nor increasing the "CPU-minutes/minute" limit.
A few weeks ago (during the last Apple keynote) we redirected all users from our german news website (www.mactechnews.de) to the app engine site (mtn-live.de/ticker/). We expected about 1000 request per second but in the first 5 minutes we received 1500 request per second. Before this event we increased the billing dollars but we weren't aware of the "72 CPU-minutes/minute" limit. It is a very simple website that just fetches some entries from the db and renders them to the html. All other resources cached "public". Here are some screenshots that shows the situation: CPU Seconds / Second: <http://my-upload.appspot.com/serve/cpusecspersec.png?key=AMIfv96C4JpGqUEGKpMjR5Cw5NUBuNi0Sj5dl3aC7tKK3PsYjQrXDtui6G0ZrAp8L9PzQzmR9mkTBejXUkhKqWdrfcfEZippkIw3o66qXjY43AxPVRdK0zaUVIC_ao4bdGNNaW9ZBf7W065nboT_BpiNVaQng5GF-Q> CPU Milliseconds / Second: <http://my-upload.appspot.com/serve/millisecspersec.png?key=AMIfv96h8j8r-JgjrZBsnuO8MOMJWhSqcLCOtXerOvfUCOBv37J-Ra9LMAcebCfcey02RlDTPj8RCzQCmLvxAvKaryskm7-BMzVXh5L8Wkl4AUWks_frF2my700zXfEP10VIqkfmuwWcEq1nYH4xWvAd3OIamKIXzw> Errors / Second: <http://my-upload.appspot.com/serve/errorspersec.png?key=AMIfv95IspnDtZlKE4LdozIY1ivRy6eUaWrrt3s5Iu0gOLqURiS6H5---Tcczn_UpLEiCa6Xar12g7fFCHaj3sn5Wq_DZeboLp8YnXSSGyEPtQGa27xjQigK5sAhXwxbARGi-3Y5KSkoZO4k08k_q0Fe8yYNcu9S1g> Instances: <http://my-upload.appspot.com/serve/instances.png?key=AMIfv95j7esCZrUNO-74AV9tBWyXp_8KFOX5c0kKMDxOek5-5b5Btmr-hw8sSQq8vMdk9Y1jhqp7rXFzyiqQ5WIeIfs6fnwoQTqxr9fVZhSHHA0J3L9DojQ1zDP9SBUG8I32HmuFOjUFCyX0t8Z9eTYB_i6kOjf3lg> Requests / Second: http://my-upload.appspot.com/serve/requestspersec.png?key=AMIfv97QiWwhl2VOW0NOnUt5lfGhxShRZ5sE0FyZTJS3Mx_HPI7YE9h4ubsHaHlmeHsIMkM65AC29DpR7jDjyzMrJW6kwnZsyAVrmU0CMBt4-wxo59gDMQXsm48UclII89Km4A7wyQnme5QZ-oZn8fxh5CgyEk7b4Q We think the problem is shown in "cpusecspersec.png": The number of CPU seconds per second is larger then 72 (it is about 100). After so many 500 errors we decided to redirect to our old ticker server (which is hosted on windows 2008). Some requests contain this dashboard logs message: Request was aborted after waiting too long to attempt to service your request. This may happen sporadically when the App Engine serving cluster is under unexpectedly high or uneven load. If you see this message frequently, please contact the App Engine team. But we really want to use App Engine for that and are planning to implement more feature like chatting on that page or some other community features... but this isn't possible at all if even the simplistic basic page can't be handled properly. So our questions are: 1) Could you please increase the per minute quota ("CPU-minutes/minute") for the app id "sy-mtn" ? (The think the next Apple keynote will take place in September so it would be great to increase the limit as soon as possible) 2) Do you see any other (per minute) quota that we could reach?
