I have been using 'DIRECT' for so long I did forget about the 'LOCAL'!!  3
it is... wow. No wonder things run faster on SSD drives, huh?

3. 

Once for the VOC, once for the Local Catalog and once for the Global
Catalog.

Would make sense -- I would guess you have 2 disk reads to 'find' the
Global Catalog - once test for the 'direct' entry in the VOC, and then
the read to the Global?

That seems very odd to me, but global cataloguing probably came from PI,
and was optimised to work fast on Primos (if you ran PI, you had special
microcode in the CPU :-)

I know Primes had blinding fast dynamic linking - okay their clocks are
very slow by today's standards, but tick for tick they can knock x86
into a cocked hat.


Changing topics within the thread, I much prefer Prime's condition
handling (inherited from PL/1) to C++'s try/catch. But that's probably
because it's not an OO type concept ...

Cheers,
Wol
