Is there any data to show how much resources my VIRTUAL HOST will take up after I install SVM & GSM on my VIRTUAL HOST?

I recently met a customer who wanted to replace the anti-virus software originally used on the VIRTUAL HOST. (TrexxMiCxx)

Of course, the VIRTUAL HOST is included with VMWARE and Hyper-V. I recommended the SOPHOS PRODUCTS to him.

He is very interested in sophos' products. He also asked me for some data, such as: how much system resources will be used after SVM & GVM are installed on the machine?
 I couldn't find any information in the community. Does SOPHOS have any official information about this?
