What is the limit on number of operations sent?

[Oliver]

In the Best Practices page:

https://developers.google.com/adwords/api/docs/guides/bestpractices

and under the Batch Operations together into fewer requests section it says:

 There are limits on the number of operations allowed in a request, and you may need to adjust your batch size to achieve optimal performance.

What is the maximum number of operations one can use with AdGroupAdService.mutate(). We can't find any documentation on what these limits are.

Hi Oliver,

You can find the recommended limits for number of operations on https://developers.google.com/adwords/api/docs/appendix/limits#general

Thanks Anash.

The documentation you pointed says that Operations per request has a value of 5,000 but then its notes say:

For performance reasons we typically recommend passing no more than 2,000 operations per request.

Which value should we use?
