CPU cost of creating an XMPP channel

[Andrin von Rechenberg]

Hey there

I have an application running on GAE with about 200'000 visitors a day (www.miumeet.com).

AppEngine is expensive, but I'm willing to pay the price for the great service

we get.

About 25% percent of the cost from the whole app come from the xmpp.createChannel rpc.

I can do more over 300 (!) datastore gets for the price of one xmpp.createChannel.

The xmpp.createChannel rpc costs me 2770ms of CPU time.

Why is that? And is that reasonable?

Hi Andrin,
You're charged for the entire life of the channel on creation.
There are several threads in the groups where this was discussed. As
I recall this is going to be changed in some way under the new pricing
model. From the pricing docs looks like it will be $0.0001 / channel
created.
