Hi Dongliang, The API guide <https://developers.google.com/adwords/api/docs/guides/rate-limits#differentiate_queue_or_rate_limiter_for_new_accounts_vs_established_accounts> you mentioned earlier is just giving a recommendation to use different throttling or queuing strategies for *new* and *established accounts *to maximize their throughput since they have different rate limits and is not necessarily differentiating between *test* and *production accounts*. Having said that, the varying speed or response time of your API calls should not be affected by whether they were executed from either your test or production account.
As for the different access levels, the main difference is primarily on daily operational limits <https://developers.google.com/adwords/api/docs/ratesheet> and shouldn't have any impact on the response time of your API calls.
