regexp: regex is much slower than java #16758
Please answer these questions before submitting your issue. Thanks!
I found Go regex is too slow. I compared the regex perf between java and Go:
Go costs 2.702s and Java costs 472ms.
Go regex is known to be slower than Java (such as ). Is there a recent case you are reporting where you have seen a major perf downgrade or are you talking about the general case where Go is known to be slower?
I don't know the current involvement but making the regex more performant is a long-shot goal, not sure we can keep track of it under an issue on the tracker.
