Hi Hao Long,
I'm Kevin from the Google Ads API Team. I'm afraid that it's not possible to retrieve performance data of all accounts in a single request. I suggest you check out parallel report downloads (Google Ads API sample, AdWords API sample) as an alternative option to looping through all accounts instead. Let me know if you have any further clarifications.
