Hey There! FYI Iv:e got a Mac Pro / running el Cap 10.11.6.0 / Vuze 5.7.6 / Btguard Prx (Stays enabled) Just a few thoughts.With a common problem l"ike this I don"t really think it matters much as long as the DL is a success in the end. Randomizing ports : Basically dumb luck / hit or miss, as some ports are off limits (already "bought out" by some gov. / corporation ) others are busy as heck , or, with any luck, empty .think of them as highways, I guess, where sometimes your bound to hit rush hour traffic. So I'm not convinced it really is a sure fire fix. Also, I saw that someone here was out of destination space and tried to move it halfway thru downloading . Bad idea. Never works. You need to go back and make room, or change the destination, but either way its best to scrap it and start over (if you make room in the old location and DL the same Tor. , you should almost immediately retrieve the % back that you had before and the Dl will continue from there. Also , stopping your DL before restarting seemed like an interesting idea, so I tried it, and honestly , I didn't see any plus side to it. I did find that going to "force quit" , quitting all unnecessary (or forgotten running apps to clear up RAM) and then "relaunch" on "Finder" helped. Hope some this helps someone..
PS. Maybe there:s a post on this already, but has anyone else noticed that if you "open" (click on multiple files arrow of Tor) while downloading, if DL speed starts to dip, that the DL speed will actually Increase !? This makes Absolutely NO sense to me! But next time your DL starts to deplete, give it a whirl! Someone once told me that Computing is "10% magic" and if I didn't accept this, I'd go nuts. Anywho, if you know WHY that works, Please tell me, ok? If it fails to work for you , well, I may have had a little too much LDS back in college;)
