Switchers are always slow, especially if your computer isn't great. I just let a simulation + automated analysis of a UC3843-based SEPIC run overnight! Be patient.

Also, try other software. LTspice is pretty quick.

You could ask in the excellent Proteus support forum over at Labcenter.

thanks for reply....are u sure it is natural to takes that much time ? cause i thought maybe i should change time step or sth which dis not affect ...what a bout pspice....can it simulate mc34063 ?

All SPICE can simulate a SPICE model.

One key piece of info here: how long is 'this much time'?

No, for a simple MC34063, that is way too much time. I just simulated the same circuit in LTspice and it took one minute to do 21ms.
