I'm not at all clear about the source of your numbers.

I benchmarked.

Your code:

<Reveal this spoiler or all spoilers in this node or all in this thread>

Result: Memory usage: 64.3MB CPU:4:54 minutes.

threads::shared:

<Reveal this spoiler>

Results: Memory usage: 21.1MB CPU usage: 7.1 seconds.

I find it hard to believe that my code even unoptimized has a 4-fold increase in total memory consumption over shared variables when only one thread has a copy of $oData and all the other threads request individual bits of data on an as-needed basis.

Don't believe; measure.

... I can't possibly see how deep copying 1G of data to each thread (10G total) would be better than 1G held by a server thread and 1K held by 10 client threads (1G+10K total). ...

You are just guessing. I benchmarked.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

In the absence of evidence, opinion is indistinguishable from prejudice.
