Consider the file http://boxen.math.washington.edu/home/jdemeyer/integral_points.sage (based on a doctest in ell_rational_field.pyx):
E = EllipticCurve([-879984,319138704]) P1 = E.point((540,1188)) P2 = E.point((576,1836)) P3 = E.point((468,3132)) P4 = E.point((612,3132)) P5 = E.point((432,4428)) t = cputime() pts = E.integral_points([P1,P2,P3,P4,P5]) print "Time:", cputime(t) With sage-4.8, this takes about 35 seconds. With sage-5.0.beta10, the same test takes about 50 seconds. I'm not aware of any serious changes to the elliptic curve code (apart from the Cremona Database upgrade). Any clues?
