restart. if that doesn't help create a new user and log in there and see if the problem persists.
I don't think your Mac has an SSD, so lags are normal if you didn't go for the Fusion Drive or the SSD option.
my imac has no ssd ... but the problem is just doing two things at a time it lag ... i seriously cant believe that .... my old acer window computer nv show lag just by doing two things at a time....by the way i was using safari to browse
Believe it.
My old early-2011 15" cMBP (quad core 2.3GHz i7, 16GB RAM, 1GB Radeon 6750M) lagged at doing just basic tasks because of a crappy HDD. Just one Safari window and having a Pages document open would bring it to its knees.
I popped in a 512GB Samsung 840 Pro after that and it went lightning fast. Booting it up from a cold shutdown only took 11 seconds, and apps only bounced once or twice in the dock to open.
Ever since Mavericks, OS X is pretty resource intensive and is heavily reliant on an SSD to work properly. If you noticed, all new Macs released in 2014 and onwards shipped with an SSD inside, or a Fusion Drive (except for the late-2014 Mac Mini). Which pretty much shows that Apple is not going to optimize OS X for HDDs.
I get the same with an SSD on my work iMac. I don't get it in Chrome. This is something I recently started experiencing in one of the Yosemite updates.
IMO its kind of silly to blame browser lag on an HDD when you can watch it happening with 0 disk activity.
EDIT: Not saying that an HDD can't cause lag but if we are talking with a strictly Safari only lag experience then its silly.
EDIT EDIT: OP, I just had it happen so I played around with it for a minute. I found closing Safari and immediately reopening it fixes it. In my attempt to screen shot no disk activity during the issue I saw in activity monitor that Safari Web Content and Flash Plug in were not responding. Screenshots don't put the spinning beachball on the screen so a screenshot was pointless.
Closing and reopening Safari clears that and it begins to function properly again. Although not saying much I am running the latest version of flash.
Oddly enough what caused this to happen was a game crashing when I closed it (become unresponsive) so I force closed it. So I don't know if the game (Elder Scrolls Online) or Flash initiated the problem. I can tell you one of those 2 things I wish I didnt need on my Mac and its not ESO.
