Did some research on the internet for you.
The tablet does have decent specs, and I even compared it to other mobile/portable devices.
Are you making sure that you're not running too many apps/programs at the same time?
Also check for updates if you haven't yet! Not updating a device causes it to be slow.
If it's none of those than you should ask other people with that device if their's performs slow too,
But of course note that everyone sees "slow" differently. If an app starts in 30 secs someone can find it slow, others say 5 seconds is slow.
