Everytime I allow software updates my ipad2 gets slower. Shall I keep my actual version?
Hello and welcome to the forum!
Please tell us which iOS version is now installed on your iPad 2? The current version is 9.3.1, and iOS 10 should be released this fall - your device is already on the lower end of the compatibility list and possibly will not qualify to go to the next upgrade.
Your machine was released 5 years ago and much has changed - see the spreadsheet below showing some specs on the iPad 2 vs. several of the most recent iDevices (

Also, take a look at this recent
Article on upgrading to iOS 9.x - many of the issues you raise are discussed. Also, downgrading to an earlier iOS may not be possible depending on whether Apple has signed off the version, e.g. for an iPad 2 (Wi-Fi only) the current signed versions seem to be the current ones (see second image below -
