[odb-users] Re: memory leak

[Per Edin]

Hi,

A transaction will require resources, be that WinAPI handles or
something else on other systems. I wouldn't care that much about it at
first.

Try not to optimize too early. Make it work first, and then, if you
experience performance problems, try to optimize them away. :)

Cheers,
Per
