The "DFA" class is quite slow for parsing dates in headers because it uses regex matching. I instead pack characters into an integer and do a simple linear search. I benchmarked this approach against other methods like Trie, DFA, SIMD, tree search. I found this method is among the fastest for this task, and remains portable, and readable. It's at least 10x faster than the previous way on x64/arm CPUs I tested. -- This is an automated message from the Apache Git Service.
