Problem make Walk Cycle

Hey everyone, i have some problem.
i make walk cycle animation.
first i animation torso up and down with Z location.
but the animation up and down with z locatin very slow at 22 frame, back to first frame.

i don’t know why, maybe i make change setting. if you have some problem please help me. Thanks :o

This is probably down to your CPU performance, you know that when you render this, it will not cycle back to 0 from 22. If you want repeated occurrences of this sequence, add a Cycles Modifier to the F-curves. I cannot see any other errors, without seeing the blend file.
