Nginx ridiculously slow with PHP+SSL combined

[Xeriar]

I am a moron.

This is embarassing, you'd think that 'siege
reported the same results...doesn't use
keepalive' would have lit a bulb somewhere.

Setting a valid Content-Length gives
a much nicer picture, and it still only uses
half the cpu:

Thank you for pointing out my stupidity, I'll go hide
in shame now. : )
