have you run my code from the post at 23.9.16 19:41 (make_array)?
Yep
And here results for your latest code. Looks like it is doing quite well.

Dear Earnest,
Thanks for running my code :)
have you run my code from the post at 23.9.16 19:41 (make_array)?
In your result the XML settles at about 2.9 MB/sec (from wire) and the text archive at about 3.8 MB/sec (from wire).
My guess from this values is, that you testes the version with make_array in the serialization functions. I realized this DEBUG thing too and i fixed it in the meantime. On my desktop workstation
The make_binary_object improved the performance a lot.
Here is the current version of the source from my homepage
