In Julia 1.9.0,
permute!
is typically faster that the internal methodBase.permute!!
, thanks to JuliaLang/julia#44941.For indexed tables in particular, using the internal method
Base.permute!!
seems to give significant performance improvements for small arrays in exchange for moderate regressions for huge arrays when compared topermute!
in microbenchmarks, though when doing slightly larger benchmarks using these functions as they are used in IndexedTables.jl, the improvements forBase.permute!!
disappear.On balance, I would say
permute!
andBase.permute!!
are comparable. In other words, I don't think usingBase.permute!!
provides any benefit, much less enough to warrant using an internal method of Base when a public method is available.This PR changes the use of an internal method with a complex implementation to a public method with a simple implementation, which is a win for maintainability and compile time.
