How to improve Mac Performance

Hello there,

 

Is anyone help to know how to improve the Mac RAM and CPU memory usage performance.

Reduce the memory usage in Finder and disable login items that take the CPU usage. I also recommend you to use Stellar Speedup Mac which has a 30-days free trial and it automatically helps you to boost the Mac performance.

That is correct, Stellar Speedup Mac is a tremendous app for boosting and managing your RAM performance.

1. Empty the caches

2. Turn off visual effects

3. Uninstall unused apps

Your Mac comes with some programs to help you decide what to do.

1. Run Disk Utility (Applications > Utilities). Use it to repair permissions and verify the startup volume. If repairs are needed, follow Disk Utility's instructions.

2. Run Activity Monitor (Applications > Utilities). If you're using swap, then your computer needs more RAM. Adding RAM is usually the best thing you can do to boost your computer's speed. Getting a faster graphics card or adding RAM to your graphics card can also significantly improve speed.

3. Running DiskWarrior or Drive Genius to rebuild your startup volume can add a bit of speed.

4. Make sure your hard drive is no more than 75% full.

I wholeheartedly endordse turning off unnecessary startup items. That can be a real drain on resources, especially on low and mid level computers.

To get there, open System preferences > Users & Groups > [your account] > Login Items. From there, just remove from the list any items you don't need.

Note if you disable swap without enough memory your machine may freeze or slow to a crawl.  The risk/performance tradeoff is up to you.

 

You can turn off swap if you have enough memory:
sudo launchctl unload -wF /System/Library/LaunchDaemons/com.apple.dynamic_pager.plist

 

re-enable:
sudo launchctl load -wF /System/Library/LaunchDaemons/com.apple.dynamic_pager.plist

 

for those who have nvram.plist:

nvram.plist check for swap enabled:

nvram.plist vm_compressor=4

 

nvram.plist check for swap disabled:

nvram.plist vm_compressor=2

 

detete swap:

sudo rm /private/var/vm/swapfile*

 

view swap status:
sysctl -a vm.compressor_mode

 

nvram config for no swap:
sudo nvram boot-args="vm_compressor=2"

 

nvram config for swap:

sudo nvram boot-args="vm_compressor=4"
