In several past discussions of this topic the consensus has been that most languages are using the PCRE library written in C while Go is using the regexp package written in Go. The PCRE regexp library is efficient but has bad performance characteristics for certain regexps. The Go regexp library is less optimized but has predictable performance characteristics with no significant dropoff. See https://swtch.com/~rsc/regexp/regexp1.html for some background.
