According to this discussion of Google App Engine on Hacker News,

A DB (read) request takes over 100ms on the datastore. That's insane and unusable for about 90% of applications.

How do you determine what is an acceptable response time for a DB read request?

I have been using App Engine without noticing any issues with DB responsiveness. But, on the other hand, I'm not sure I would even know what to look for in that regard :)
