gnucap speed

Just for fun, this simple inverter oamp circuit:

*prueba del ADA4898
.load ./dio.so
.include ada4898.cir

v2	1	0	sin(0 0.1 1k 0 0 )
r1	1	3	1k
r2	3	4	20k
v3	6	0	dc	5
v4	7	0	dc	-5					
r6	4	0	1000
x1	0	3	6	7	4	ada4898
.print tran v(1) v(4)
.tran 	0.01m 25m
.end

On gnucap: 0.719 seconds
Same circuit on QUCS: 65 seconds.

I do not understand why there is such tremendous  time difference. Same 
stop time, same step size. Gnucap goodness or Qucs badness....

Thanks,

Ramiro
