The retry interval base value is retry_initial_delay Adjust the value like Payjp.retry_initial_delay = 4 The smaller is shorter.
The Maximum retry time is retry_max_delay. Adjust the value like 'Payjp.retry_max_delay = 32'
The retry interval calcurating is based on "Exponential backoff with equal jitter" algorithm. See https://aws.amazon.com/jp/blogs/architecture/exponential-backoff-and-jitter/
