How to know what slows down our computer and how to effectively solve? Why do we see rainbow wheel and how to get rid of it? What is the best diagnostic program mclane company for our Mac? If the Mac is really slow, it is best to run Activity Monitor and look at memory usage, CPU usage (CPU) and disk activity. CPU, or processor
First, we look at the CPU tab. First, shut down any applications (using the shortcut CMD + Q). Run Activity Monitor and let all the processes, we sort the list by percentage of utilization: they should all processes consume mclane company less than 5%, normally in most of the processes in the range of 0-2% CPU performance. If we look at the idle processes and sees the majority of 95% or more, everything is fine. If the processor is busy for dozens or hundreds of percent, then you can easily find the application process by name at the top of the table. That we can end it. Processes "mds" and "mdworker" We'll run those related to the indexing disk for backup, abruptly jumps for a while, but after a while it goes back to less than one percent. When we have completed all applications, none of the processes should not use the processor more than 2% for longer than 5-10 seconds except those "mds" and "mdworker".
If we see a green sign free memory in the hundreds of megabytes, it's okay if the number falls below 300 megabytes is the right time to supplement memory or certain applications. If even a relatively free memory (and that does not happen) is a slow Mac, it remains a last resort.
Although Mac charged will be up and running me dozens of applications simultaneously, Mac goes without major incident. RAM I even fell below the critical 100 megabytes and yet the rainbow wheel just could not discover. So he has a "sound system". Disk activity mclane company
What do we delude ourselves, Lion and Mountain Lion are optimized for SSD in the MacBook Air and MacBook Pro with Retina display. In a healthy system, read and write data around zero or the value of jumping between zero and the order of kB / s If the average activity of the disk moves continuously in the order of MB, for example, 2-6 megabytes / sec. It means that some of the applications of the disk drive reads or writes it. Typically, this is one of the processes with higher CPU workload. Apple has its applications very well optimized, so most greedily behave in this way the "third parties". It's mclane company not our fault, but the fault of the developers of such applications insatiable. We have three possibilities of defense:
That deletes unnecessary files, last worked on Windows 98 Provided that a program during installation or in the actual functioning creates its temporary (temporary) files on the disk, so it is likely sooner or later you will need. When these "unnecessary" delete the file, the program will produce the same again and our Mac so only slows down when their re-creation. So the Mac (and better not Windows) not cleaned from unnecessary files, this is nonsense.
So this is bullshit. Our computer has 4 GB RAM and processor dvougigahertzový. With normal use, the computer is running in the background 150 simultaneous processes, rather more. When you turn off four of them do not recognize it. You will not help you or one full percentage point of performance, if we have enough RAM, nothing will change. Video will export the same time and the game will show the same FPS. So do not turn anything on your Mac, it will add more RAM. This will significantly speed up switching between applications. How can speed up Mac? 4 GB of RAM? Rather more
Mountain Lion grassroots work with web and email devour less than 2 GB RAM. So on older machines when you add 4 GB, you can still use iCloud on almost all Macs produced since 2007 processor from Intel. A seriously now. If you want to have an open iPhoto (download photos from Fotostreamu), with a dozen Safari tabs with Flash video, Photoshop or Parallels Deskotp is 8 GB RAM minimum, and the 16 GB RAM is pretty cool, utilize it. If, of course, the computer can use. To really accelerate? Faster disk
The disk is the slowest part of our computers. He always mclane company was. U oldest mclane company MacBook (white or black plastic) or aluminum are used in small disks. Smaller capacity of 80, 160 to 320 gigabytes drives are significantly slower than the current 500 to 750 gigabytes or than any SSD. So if you want to mainly increase the capacity mclane company at its white MacBook is 500 gigabytes for about 1,500 CZK excellent choice. If we want from your favorite four years old MacBook to make a real cannon, mclane company invest a few grand to SSD. At a cost of around CZK 4,000 can buy SSD drives, which significantly speeds up the whole
