Unable to sign up for performance edition trial account.

Hi Mrinalni,

All trials are Professional Edition.

You can sign up for a free Developer Edition at the Developer Community (https://developer.salesforce.com) which

has all the Enterprise features.  This is great for testing out the feature, but don't start putting any actual business

data in the Dev Org since that is not going to be converted to your Production org when you decide to sign up.
