Roughly how many commands are in each transaction ?  Are we talking tens or 
hundreds or thousands ?

Roughly how many concurrent users do you have ?

How is access to your database shared ?  Are all your users opening the 
database across a network using a Windows share ?

You might already know this, but SQLite does not support any locking except by 
locking the entire database.  So if one use has a transaction half way through 
writing, no other users can do anything.  There's nothing you can do about this 
with any combination of hacks.
