ive running an almost stock Slackware 10.0 distro for a while now and i thought that i'd experiment and move from the 2.4.26 to the newest kernel 18.104.22.168. i downloaded a fresh source tarball from kernel.org and used menuconfig to add in just the options and modules i need for my system. i then ran "make" and "make modules_install". i copied System.map and arch/i386/boot/bzImage to my /boot directory and soft-linked to them for lilo.
parts of "ls -l /boot"

now, it compiled and booted fine, however, i am noticing a significant decrease in speed. i am running an Athlon XP 3200+ Barton on an NForce2 chipset (ABit NF7-S motherboard, nothing OC'd). i notice this during start up (ldconfig and such run noticably slower), as well as normal stuff in X (im running Gnome 2.6 right now). i have my CPU option set specifically for the Athlon in the Processor family section. everything works without error, but its just noticably slower than before.
