I can't find any information regarding Braintree java SDK performance. In general, almost no information about Braintree throughput and timings at all.
Root issue: when we have customer's peak (about 100 at the same moment) and application tries to lookup all of them (GET /customers/{id}), operation timing goes extremely high.
Average time for the operation - about 1s. At the peak - up to 14s. I even don't know whether it's ok or not for Braintree.
Tried to find out some tuning options inside the SDK, but unsuccessfully. Looks like it uses only direct HttpUrlConnection with no pooling or something like that.
Any link will be appreciated. Thank you!
