Issue 1123: regression: solve(diff( )) is much slower since 0.5.15 http://code.google.com/p/sympy/issues/detail?id=1123
Comment #5 by mattpap: The problem was in new roots() method - it was checking not enough trivial cases and used functional / square-free decomposition unnecessarily, making the results overcomplicated (so that simplify hanged on multivariate gcd computation). Patch was sent for review: http://groups.google.com/group/sympy-patches/browse_thread/thread/94773f692519abaa The patch fixes this issue, however more improvements to roots() function are needed (especially roots() logic needs to get simplified and more trivial cases added).
