verify your running VM consuming SWAP memory ..Just click on VM and in the right side click on resource allocation you can see swap total memory status....if it is taking Swap space than you can do these step to increase performance..
1) Install VMware tool on both VM
2) In this vm has 2 ram you can decrease RAM 2 gb to 1 or 1.5 on that vm and increase its share with HIGH ..just right click on VM ..Edit.. in the otpion tab ..click on RAM there you will find share option and u can set this as HIGH.
3) Same you can do with VM 1 ...check for some time .....
Issue should be closed.
Thanks
