Grunt takes all CPU resources from Vagrant VM and VM stops responding - macos

Question

I ran Vagrant/VirtualBox on my MacBook Pro
OS: Yosemite 10.10.5
Model Identifier: MacBookPro11,1
Processor Name: Intel Core i5
Processor Speed: 2.4 GHz
Memory: 8 GB
After few requests it stops responding and I can't even halt it or ctrl + c it via terminal. All I can do is go to VirtualBox and to shut down it.
Installed versions:
Vagrant 1.7.4
VirtualBox 5.0.4
grunt-cli v0.1.13
grunt v0.4.5
Vagrantfile:
$ProjectName = 'projectdev'
VAGRANTFILE_API_VERSION = "2"
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
config.vm.box = "ubuntu/trusty64"
config.vm.box_url = "https://atlas.hashicorp.com/ubuntu/boxes/trusty64"
config.vm.hostname = "#{$ProjectName}"
config.vm.network "forwarded_port", guest: 80, host: 8888
config.vm.network "forwarded_port", guest: 5432, host: 15432
config.vm.network :private_network, ip: "10.0.0.10"
config.vm.synced_folder ".", "/vagrant"
config.ssh.username = 'vagrant'
config.ssh.password = 'vagrant'
config.vm.provider "virtualbox" do |v|
v.memory = 2048
v.cpus = 2
end
#config.vm.provider "virtualbox" do |v|
#v.gui = true
#end
config.vm.provision :shell, path: "infra/bootstrap.sh"
end
Vagrant::Config.run do |config|
#config.vm.share_folder "bootstrap", "/mnt/bootstrap", ".", :create => true
config.vm.provision :shell, :path => "infra/postgresql.sh"
# PostgreSQL Server port forwarding
#config.vm.forward_port 5432, 15432
end
Thats how top looked at the moments its stopped responding

Is there anything to be done for Grunt to take less resources and not kill my VM ?

Answer 1

So seems I found an answer to my problem!
On MACs you should turn NFS SYNCED FOLDERS on
Use all CPU cores
Don't skimp on memmory for Virtual Machine ;)
Also, I haven't tried this yet, but may be also a good optimisation!
