in thread Data structures in Perl. A C programmer's perspective.

When people talk about linked lists “storing data all over the place,” what they are really concerned about is locality of reference, i.e. minimizing the probability of a virtual-memory page fault ... which involves stopping the process in its tracks, doing a physical I/O to retrieve the page from a spinning disk,

Downvoted: Locality of reference has exactly zero to do with page faults; zero to do with physical IO; and zero to do with spinning disk.

Your whole post is total misinformation.


With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
