Thanks for your answer. It's my Fault,get_result_df in Suggested code takes only 5ms, It's very fast. The real data time is not linear, only the specified time period. I'll resubmit a question.

You haven't spoken to this in your question. Will the real data always have a datetime index that's linearly uniform? And have you measured both the bisection and interpolation implementations? | |
