my slow results are much faster than yours

Yes. This is 32-bit 5.8.9 on 64-bit Vista on Core 2 Quad @2.4GHz: 

## full hash
C:\test>\perl32\bin\perl.exe 909437-1.pl
Lock hash took 1.153 seconds

## refs my way
C:\test>\perl32\bin\perl.exe 909437-2.pl
Lock scalar ref took 3.057 seconds

## refs your way
C:\test>\perl32\bin\perl.exe 909437-3.pl
Lock scalars ref took 3.473 seconds

And 64-bit 5.10.1:

C:\test>909437-1
Lock hash took 1.189 seconds

C:\test>909437-2
Lock scalar ref took 3.285 seconds

C:\test>909437-3
Lock scalars ref took 3.434 seconds

Maybe the internal semaphoring has improved substantially in 5.14? Time to consider an upgrade.

Does 5.14 have much else to make the pain worth while?

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.
