Like NagangoudaPatil mentioned, is VMware tools installed? If not, install it on both VMs and reboot.
What size did you allocate to the C drive on the VMs? What is the swap file setup for? System Managed vs manual settings?
Do each of the VMs have only 1 vCPU with 1 core?
Also, how are you accessing them? Via the console or via RDP? The console may seem slow with mouse movements, but if you RDP things are typically faster.
