How to improve performance in EXSI VMs ?

[madhanSakthi]

Hi,

I am using EXSI VMs to install and test my product. I have my own application to automate the installation of setup and perform the testing.

When i do the same in physical machine , the installation hardly takes one hour to complete. But when i do the same in VMs, it is taking more

than 5 hours. I have the same configuration in both VM and phusical machine. What could possibly affect the performance in VMs ?

How can i improve it ?

Thanks.

A few questions come to mind:

• What sort of storage are you using?
• What is the server spec and how many VMs are you provisioning? Is the machine being over taxed?
• What is the guest OS? Is it a supported OS, and do you have VMware Tools installed?
• are you able to identify any particular processes that are taking a long time?

Hopefully with a bit more detail we might be able to help you find an answer.

I have enough resources on the server. The only problem i can see is, only when i use my automation application to install the setup it is taking more time.

If i install the setup manually, it takes the normal time. But this is not the case in physical machines.

Check network, cpu, memory and storage usage with esxtop.

Below graphic also shows a good overview.

In particular I would look into high %RDY values.

Did you Monitor performance while installing your application.
