Well, I first posted this thread because I was stunned by how slow the 
single-file load
was. I felt I was doing something stupid, and I thought someone would 
point out whatever
stupid thing I was doing.

When no-one posted anything that helped, I continued experimenting, and 
saw the difference
with the multi-file load. The difference was also the difference between 
a tool I could use and a tool that was infeasible for a majority of my 
tasks.

I don't know if the single-file load method can be speeded up or not, 
but to be quite honest, now that I've got a method that is fast enough 
for me, I'm happy, and I don't care about single file so much anymore...

That's why I posted the whole shebang to the mailing list. I see from 
Matt's reply that it wasn't the reason.

It was mysql. Dunno why sqlt didn't pick up the relationships, I thought 
I installed the latest version from CVS. Anyway 
DBIx::Class:Schema::Loader picks them up for me quite nicely, and since 
the resulting schema is also faster to load, it's a complete no-brainer.


I want to thank all the authors for a wonderful tool. You've saved my 
bacon in the past few weeks.

Thank you from the bottom of my heart.
