traffic slows down and almost halts on the router

traffic slows down and almost halts on the router

We have a router (2600, IOS ver 12.2) and when I configure the internet (serial) and internal port (ethernet) for Netflow support and configure the router to export Netflow data (source is the internal interface) , the traffic slows down or stops at all.

Should I configure the internet interface at all ? Which interface do you recommend to be the source of the packets ?

Thanks
