I recommend looking at Appstats, and verifying whether you are performing batch gets across entity groups. I have not met an app yet that is unable to get acceptable HRD performance.
I should note that apps built on M/S have (usually unintentionally) been optimized for the M/S performance characteristics. It makes sense that some apps may need to or want to make adjustments before migrating to HRD. I should also point out that I have yet to meet a developer whose not happier on HRD and migrating their app. You may well be the first (although I'm not trying to imply that you are the only one)... :) On Thu, Aug 18, 2011 at 12:11 PM, thstart <thst...@gmail.com> wrote: > Let me share my experience. > > I was developing an AppEngine app for a year. > It was very fast (extremely fast), with latency > 1 sec. > When High Replication data-store was released I decided to give it > a try and switched to it.
