How to get rid of brakes on Mac OS?

Question

macOS

I have a Macbook Air 2014 with 4GB of RAM. Process i5. YosemiteOS. Works great, no brakes, but! When I start working on it and run it on several desktops: Photoshop, mamp, chrome, sublime and some other social network clients, after about an hour of work, slowdowns begin during various transitions in the system (approx. between desktops). At the same time, there is enough free operatives, the percentage is loaded by 50 percent. And God bless them with these slowdowns during the load, they are not noticeable during fast switching, the problem with them pops up after the end of work. After disabling all of the above programs, killing their processes and completely unloading the system - the brakes do not disappear anywhere! In terms of resource monitoring - everything is just perfect, no loads. All heavy programs are turned off, but the brakes during transitions between the same tables can be eliminated only by rebooting. Clearing the RAM through the terminal does not help either.
Advise what can be done and what is the problem buried? Constant reboots are annoying.
Thanks in advance!

Answer 1

The problem has long gone by itself with system updates, this does not happen again! Mac is still the same, flies and works with a bang)

Answer 2

I don’t believe that with an open layout in Photoshop and Chrome running, “free RAM is enough.” Sooner or later, the whole thing will begin to swap itself, and push others into the swap. From here it is possible and "residual" brakes, after closing applications. In my opinion, now 4 gigabytes of memory is not enough for comfortable work with such a set of applications.

Answer 3

Mac OS X currently requires a minimum of 8GB of memory to run. 4GB is purely in the browser to sit. Watching how much memory is free or busy is useless. Just try increasing the memory and see the difference.

Answer 4

As an experienced Vanga, I’ll say that you don’t have enough operatives, you need at least 8 in your case, and 16 for comfortable work, you took a classic travel laptop, besides, in its most budgetary part and try to squeeze out of it what a full-fledged worker should do comp.

Answer 5

In the latest releases of the new version of the operating system, there are always small nasty bugs on semaphores and other multi-valued blizzards, which are cleaned out over time. What you are seeing is most likely not "brakes", but waiting for events on all kinds of semaphores inside the OS system components. Very often, they are waiting for some kind of event with a long timeout, for example, related to the network or the reaction of iron. After intensive work, as a result of code errors, some system components enter states in which they check something there many times without meaning or simply hang, and each time waiting for the reaction of this component takes a full timeout.

Answer 6

Watching how much free memory is useless. Since the MAC will always keep some free memory. Even if you put 16GB, then there can be as much free memory as with 4GB with the same set of applications.
At first I thought that there was some kind of memory leak. But after numerous benchmarks, tests, reading articles, I realized that working with memory in MAC is not the best. I think that on small amounts of memory, Windows copes much better.
For MAC - the amount of memory is 8GB, this is the minimum. Preferably 16GB.
