Whats the batch request limit for Facebooks Graph API?

Does anyone know whats th开发者_如何学JAVAe limit for batch requests when using FBs graph API? From their documentation:

Limit

We currently limit the number of batch requests to 20.

That's not clear. Is that 20 per 600 seconds? Per day? Total for one app ever?

It is 50 now. 50 request/batch

---

It means that 20 individual requests are allowed to be batched together into a single batched request, which saves you from sending 20 individual http requests over at the same time.

If you have more than twenty (20) you can build an array and then break them into groups of 20 or less and loop them thru your PHP in one "session". We have one app that will run 600 - 700 OG requests but it is sloooooooow, up to 300 seconds, some times, depending on FB.
