Speed of lsim

Hi. I am a beginner of Octave, and I need some help to accelerate
As I want to simulate the response of a linear time-invariant state
to the arbitrary input signal, I tried to use "lsim". But I feel it's
too slow.
For example, it took about a minute to solve the step response of a
1st order lag system, 1/(1+s).
My Octave is version 2.1.36, my PC has Pentium-III 1.2GHz and 256MB-RAM 
and OS is Windows XP Pro.
I'm waiting for your good advice.
