I’m not sure either of these will outperform sqlite on CGo, but both of them should eliminate the CGo overhead and might give you some more room. P.S.: The latter is a bit unorthodox in that it contains separate code for each architecture supported by Go, most likely a reflection of the method of the automated translation.
