Both are compiled only once - when executed for the first time - and reduce the compilation cost by caching the execution plans and reusing them for repeated executions. Both allow automatic re-compilation if there is any change applied to them. Package is the best because once if you complied the package means when ever where ever you called that packagfe it won't recompile again but for procudure each and every time when you call the standalone procedure it will complire, so if you use the package means the performance will increase.
