Efficiency of path searches

While reading some papers and presentations on search methods, I discovered a contradiction regarding the recommendation of using path searches. The presentation Optimizing PI AF Server and PI AF SDK Applications for Performance and Scalability from 2013 rates path searches as best practice (slide 76), after improvements performed in AF SDK 2.6. However, in PI AF SDK Guidelines from 2015, also targeting AF SDK 2.6, attribute path searches are listed in the caution section (page 15).


Which recommendation is correct? Which are the most efficient search strategies? Appreciate it if anyone has any experience to share, maybe also with some test results.
