I use vmware a lot for development and networking experimentation’s. My system is getting very slow when 4 instances of vmware are trying to access (destroy?) the hard drive. Recently one of my coworker told me that was possible to speed up vmware by 40%. A very interesting tuning , it avoided me to buy a new computer :-)
The principle of this tuning is to use the RAM as the temporary directory.

Step 1: Edit VM config file

The file is usually located at /etc/vmware/config
Edit the file and make sure you have this line in it

tmpDirectory = “/dev/shm”

Step 2: Mounting /dev/shm

Edit /etc/fstab and add the following line.

tmpfs  /dev/shm tmpfs   defaults,size=1G,noatime  0 0

I’m getting really good results by setting the size of the partition as the same size of the ram I have.

Step 3: Mount and Run

Now mount the partition and give it shot.
You will see a huge difference.

You may have some other tricks to make it smoking faster, please share it in the comment section!
