Update: I pulled the reCaptcha jar out of the project just to make sure there wasn't something funky in it and I redeployed. Still no change.
>From my logs for a startup request to main page which pulls one string from memcache and the Session object and displays page, I get the following in my logs. Still no API CPU cost even though memcache is hit and a Session object is retrieved and pending_ms seems really high. Perhaps the increase in number of instances starting up is because of this dramatic increase in latency (he ponders???). Hopefully it like many things with GAE it will magically correct itself or I'll figure out I've screwed something up. ms=12561 cpu_ms=3740 api_cpu_ms=0 cpm_usd=0.104161 loading_request=1 pending_ms=3337 ms=14286 cpu_ms=3520 api_cpu_ms=0 cpm_usd=0.098050 loading_request=1 pending_ms=6769 ms=16225 cpu_ms=3685 api_cpu_ms=0 cpm_usd=0.102637 loading_request=1 pending_ms=7813 On Wed, Feb 9, 2011 at 1:40 PM, Stephen Johnson <[email protected]>wrote: > Hi Ikai, > It looks like I must be the only one seeing these strange things.
