Hey guys, i have recently erased my OS X partition and installed Lion as the earliest available one for my macbook (late 2011) and a day after i installed Yosemite. Oddly enough Lion was noticeably faster in some regards, like booting, opening most apps (Appstore especially), spotlight worked faster and so on. Is there any reason why Lion would perform better than Yosemite on a fresh install and is there anything i can do about it? P.S. the differences aren't huge but they are noticeable, and it makes no sense that the newest OS performs worse than a 4 year older one.
