Large Data Import

[eluser]Unknown[/eluser]
Hey Guys,
I am working on a script that needs to loop through a 1GB XML file and import about 9 million records into a mySQL database. I'm using XML Reader to get through the file and CI gets through it at a good pace, I know my bottleneck is with the SQL inserts and queries. Does anyone have any PHP advice to speed up the script? Is CI a bad idea in this case, should I just be using straight PHP?

Thanks!
