If you speak about LTT, it adds hooks to kernel. These hooks are always active even if you have to do as little as compare variable for (in-)equality. In some contexts you would avoid any extra job - just think about timer interrupt. OTOH crash dumps should not impact performance of running kernel in any way. At least I do not see how it is possible. -andrej
