Client Library performance

[lesv]

I'm working with a customer who is moving from MVM's using Objectify and the GAE Bridge to Flex using google-cloud-java Datastore API's.

The customer is reporting that using Objectify on MVM takes about 6-10sec and doing the same thing with google-cloud-java takes 40+seconds.

@garrettjonesgoogle @omaray FYI @GoogleCloudPlatform/cloud-datastore FYI

A 6x performance degradation is pretty large, marking P1.

@lesv Do we know what operations are involved? I can try looking into benchmarking this, but it's difficult to do in the abstract.

gRPC Java 1.5 library was released claiming a 2x performance improvement. Not sure if it a disappointment that Datastore isn't gRPC or not.

Reading a lot of data. (i'll find something and send it to you.)

Hi @lesv, do you have any update on this (i.e.whic operations are involved)?

[lesv]

I will forward you the conversation.
