As a counterpoint, consider that random recommendations from the internet can easily get outdated.

So apparently, transparent hugepages have some issues in their current implementation that can cause big performance losses in some cases. Seems to me like that's a bug, and I see no reason why that bug couldn't be fixed in the future.

By following random recommendations, you get into situations where the underlying problem has been fixed for ages, but people still cargo-cult some workaround that actually makes things worse with the new implementation.
