I hope that Mikael knows of some native Linux tools for this. However, Intel did announce Vtune for Linux recently (might still be in beta test), and there was a SuSE patch for it posted at kernelnewbies.org also. See:
http://www.linuxhardware.org/comments.pl?sid=364&cid=530 http://www.linuxhardware.org/articles/03/01/17/1633229.shtml http://kernelnewbies.org/kernels/SuSE81/SOURCES/patches.i386/50_vtune-ia32 (warning: this is for 2.4.19)
or google for "+vtune +linux".
