Hi Prashant,

There are a couple of questions here:

1. Has your hardware been configured for optimal I/O throughput?
2. Have you installed XenTools on the VM?

Slow VM Template Deployment:

Initial Template download from SS is dependent on the SSVM, CPU, RAM and Network speed. Check
that all of these have been configured to optimal speed & size. Initial template deployment
is "slow" as the template needs to be copied from SS first. Subsequent deployments should
be faster.

Slow VM Reboot:

This is dependent on the hardware configuration and whether PV drivers (XenTools) have been

Kind Regards,
