Rest Api Performance

General
1

I’d like to improve performance of launching a Rest API.
I have to launch about 70K times the same Api with different parameters through a Data Collection. The duration of a single rest Api is about 0.7s.

  1. Can I do something for reducing this time? Can be useful disabling log or something like that?
  2. After about 4K executions, the run ends with 4K of rest Api completed and 6/7K of Rest Api Uncompleted. How can I avoid this?

Thanks in advance
