Newly bought ipad5 is lagging

I have just bought ipad 5 and soon after activation i have upagraded it to io11

but this ipad is lagging... and i am surprised to see this...,

is that ipad issue or ios11?

Help me out ....

I am guessing "iPad 5" means the fifth generation of iPad, which Apple calls "iPad Air".

The iPad Air was released in late 2013, and discontinued in March, 2016. So I am guessing you bought it as a previously owned device.

All this aside, it is hard to know what "lagging" means exactly. It might mean, for example:

When I type keystrokes, the iPad responds slowly (e.g., echoing the keystrokes on the screen).
When I attempt to access the internet, sites load slowly in Safari.
Videos play slowly.
When reading an iBook, pages turn slowly.

Clearly we need much more information.
