If you're just using AWK features, mawk is still the fastest. GoAWK is faster than awk in most cases, on a par with gawk, but still not as fast as mawk (see https://benhoyt.com/writings/goawk-compiler-vm/#virtual-machine-results https://benhoyt.com/writings/goawk-compiler-vm/#virtual-mach...) ... except for scripts that make heavy use of regexen. Unfortunately Go's regexp package is still quite slow. You could also try frawk, which is a JIT-optimized AWK written in Rust -- it's really fast, and shares some of the CSV features (but not the @"named-field" syntax). But for most everyday usage, even for large inputs, GoAWK's performance is quite sufficient. The CSV support, and its use as a Go library -- they're more important to me than raw speed at this point.
