i have a doubt in creating a vm on vsphere based on the application we are going to run.
Hardware : HP Proliant DL385 G7 with 24GB of RAM and 2TB of HDD, 16CPU'sX 2GHZ processor
i installed vsphere-4.1 on this server
## i installed a vm, ubuntu-10.10 server with 4 cpu, 6GB ram and 100 GB of HDD.
## i installed matlab on this vm.
## i got reply from the users saying that when they are running simulation it's performing slow compared to their desktop's (which are I3 processor with 4GB DDR3 RAM)
i don't understand why this it was slow. i can't analyze weather i didn't provide sufficient resources to the vm or i don't have proper HOST (vsphere H/W).
can any body tell me how to calculate virtual machine configuration depending on the applications we will install (if we have sufficient hardware resources in the server)
