Yes, for an average .ini file I think you will find them to be 1K or under. ODBCINST.INI is the largest one on my system and it's only 4K

Now consider reading 100 items from a 7K file. You now just read 700K but their is network overhead every time you make that call. Which means you get that overhead hit your system 100 times as well.

Not that it's crippling slow on a modern hi-speed network, but using another method for slow links might be better.
