[c-nsp] Strange 7600 behavior

Guys,
I´m trying to replace one 6509 with sup7203bxl to 7600 with RSP720-3cxl, but
I´m getting strange cpu usage behavior.
With a very few traffic, about 400Mb, I got the router consuming much more
cpu, due interrupts, than sup7203bxl.
We are using SRE3, but also tried SRC6 and SRB7.
The configuration is exactly the same.
Am I doing anything wrong? Or LAN modules have a worst performance in 7600?
