What version of Android are you running?To find out...Settings> About tablet> Android version...If your not up to date then I'd suggest updating your tablet, if you are then maybe it's time for a factory data reset...Sent from my Paranoid Nexus 4 using Tapatalk 4 Beta
As JayJ suggested a "Factory Reset" is always a good option, but just to make sure, I will have to ask, since you did not state the obvious first option with a sluggish N7, have you tried restarting the device or what is referred to as a soft reset?
Before resetting my N7, I'd check and make sure the slowdown isn't a network problem. I'm on cable service and sometimes the whole network will slow down if several people go online at the same time. A lot of devices on your local network could also slow you down. Try rebooting your router.
