From: Ralph Doncaster <ralph@xxxxxxxxx> Date: Tue, 17 Jun 2003 18:11:00 -0400 (EDT) My (obviously incorrect) assumption would be that fib_validate_source is responsible for rp_filter, and turning it off would lead to only a 5% performance increase. fib_validate_source() with rp_filter enabled causes an extra fib_lookup() to occur for each packet. |
