Your query will probably fetch more then 25 Action objects. Fetching all those Keys is fast. Fetching all the complete objects is slow, you fetch a lot more then you need.
If you iterate over the GQL query, no fetch, that requests full Action objects (SELECT * FROM ACTION.......), the objects will be fetched in batches of 20. You then only fetch a few more objects then needed. Performing XX_multi operations on the memcache will also help reduce the response time. 2009/8/23 bvelasquez <bvelasq...@gmail.com>: > > http://pastie.org/592489 > > If you can help me answer this question, I would appreciate it. > > The above code takes the following ~ time: 1370ms 1725cpu_ms > 670api_cpu_ms. > > Changing the query to return the Actions bumps it up to : 2311ms > 3050cpu_ms 1018api_cpu_ms > > Changing the Action.get() to use the list of Keys from the SELECT > takes ~ 2000cpu_ms. > > I was surprised that doing an individual get on each key was faster > than passing the array into get or returning the actions with the > query. > > What are your suggestions for optimizing this, if anything is > obviously wrong or maybe there is another way completely for achieving > the same results, which my limited experience is not telling me. > > A couple notes.
