With an average runtime of 18.7674, this implies 1876ns per trace, which is far in excess of the 370ns claimed in doc/developers-guide/tracing-cln-performance.md. We also add a tag in there, so we measure that! Results on my laptop: real 0m18.524000-19.100000(18.7674+/-0.21)s user 0m16.171000-16.833000(16.424+/-0.26)s sys 0m2.259000-2.400000(2.337+/-0.059)s Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
