Macbook Air mid 2012 running slowly

So, I've got this macbook air(mid 2012), sometimes it runs perfectly and smoothly , but there are some day that lags are incredible, browser takes its sweet time to start(I'm using google chrome, opening new tab takes several seconds, when i type something it, once again, appears with 2-3 seconds lag) , itunes lags as ****. When performance is ok, on startup (before logging in) wifi is connecting instantly, but when it starts running slowly, wifi connects like 2-3 minutes after i log in.(that's the only regularity, except slow performance, I've spotted so far).

I've reseted SMC and PRAM. I've also run Apple Diagnostics.

MacBook Air, OS X El Capitan (10.11.3), null

Rid the MBA of CleanMyMac3. It is not needed, will slow your MBA and possibly delete the wrong files and corrupt your MBA. Usr these instructions;

http://macpaw.com/support/cleanmymac/knowledgebase/how-to-uninstall-cleanmymac-3

Also get rid of the torrent application.

Internet Explorer is old and unsupported. Do you really have a need for it?

Ciao.

Will do(safari extension is related to parallels desktop), but that's isn't an issue. I've had those problems before i've installed parallels and cleanmymac

Hello v.e.r.,

Your EtreCheck report will be most useful if you don't restart before running it. Restarting erases some of the diagnostic information that EtreCheck reads. It is best to run EtreCheck during or shortly after the machine experiences a problem.

But I think that your problem is most likely related to running Chrome on a 4 GB machine. Chrome takes a lot of RAM. I have seen it take 2.5 GB without much effort. You don't have 2.5 GB to spare. Your SSD is keeping the lags to a minimum, but there is only so much it can do. Safari is less RAM intensive than Chrome.

When you see a beachball cursor or the slowness is especially bad, note the exact time: hour, minute, second.

These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.

Launch the Console application in any one of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad and start typing the name.

The title of the Console window should be All Messages. If it isn't, select

SYSTEM LOG QUERIES ▹ All Messages

from the log list on the left. If you don't see that list, select

View ▹ Show Log List

from the menu bar at the top of the screen.

Each message in the log begins with the date and time when it was entered. Scroll back to the time you noted above.

Select the messages entered from then until the end of the episode, or until they start to repeat, whichever comes first.

Copy the messages to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.

The log contains a vast amount of information, almost all of it useless for solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.

Please don't indiscriminately dump thousands of lines from the log into this discussion.

Please don't post screenshots of log messages—post the text.

Some private information, such as your name, may appear in the log. Anonymize before posting.

When you post the log extract, you might see an error message on the web page: "You have included content in your post that is not permitted," or "The message contains invalid characters." That's a bug in the forum software. Please post the text on Pastebin, then post a link here to the page you created.

If you have an account on Pastebin, please don't select Private from the Paste Exposure menu on the page, because then no one but you will be able to see it.

Chrome isn't the issue in this case, as I said when computer isn't lagging, chrome like everything else run smoothly.
