Lathes can render quickly if you use a linear or quadratic spline.
Cubic splines are little slower. A lot of it depends on how many
points for the spline are specified and how well behaved it is.
If you specify a lot of points or require sharp bends from the
spline is can slow things down. For a simple cigar shape I see
no reason why it would not render in an acceptable amount of
time.
