Although WRI refused to accept this behavior as a bug, it seems that they fixed it in v. 11.1. For this example Integrate with assumptions is 40% faster than without. Can someone confirm this?

@xzczd Yes, according to them it is not a bug. As a workaround they suggest to use TimeConstrained[Integrate[...], Infinity] , that's it.

| Jan 4, 2016 at 3:14 | comment | added | xzczd♦ | @vsht Well, "backslide" is just a tag (coined by me) to mark those backslides/backsets/degenerations/degradations/regressions/retrogressions in newer versions of Mathematica and I think this issue definitely fits into this category. I guess WRI just claimed it's not a bug, right? | |

| Jan 3, 2016 at 18:28 | comment | added | vsht | @xzczd: Since it is officially not a bug, could you please remove the backslide header? | |
| Jan 3, 2016 at 18:28 | comment | added | vsht | @bbgodfrey You are right. I updated my question to include WRI's statement. | |

| Dec 30, 2015 at 10:40 | comment | added | bbgodfrey | @vsht I am not sure that timing out a bit sooner constitutes a bug. Please see the most recent edit to my answer. Best wishes. | |
| Dec 29, 2015 at 21:03 | comment | added | vsht | It's now CASE:3500395, although the backslide has not been confirmed yet. | |
| Dec 29, 2015 at 15:20 | comment | added | vsht | Ok, I've just sent a bug report to WRI with a link to this question. Let's see what they will say. | |

| Dec 29, 2015 at 12:11 | comment | added | xzczd♦ | I think this should be called a backslide. In v9.0.1 both of the 2 samples give the correct result (The latter is still slower though ): i.sstatic.net/SYKrv.png | |
| Dec 28, 2015 at 18:32 | comment | added | vsht | So should I add the bug tag and report this to WRI? To me, this behavior doesn't seem to be quite ok... | |
