After this you would recognize the decrease in Ubuntu startup time. So just follow the guide to Speed Ubuntu Startup by Disabling Startup Applications.
Firstly let’s try to figure out what causes the slow performance of your Ubuntu Linux. Overtime when you install a lot of applications, these apps start every time you boot up your system increasing the number of startup programs. Startup programs is a list of programs and apps which after installing ads themselves to the list.

Manage start-up applications:
Go in to your Unity Dash and search for Startup Applications. clicking it would open up a list of Applications. These are the applications which are automatically started once you boot up your Ubuntu. Now disable the applications which you think are not required to started up every time you boot in your Ubuntu. Simply uncheck the application and close.
But wait, what if you need some specific application and want to decrease the startup time also, there’s a solution for you. You could delay the start time of that specific application. This will in return free up the resources on startup and the application would be loaded after some specific time. To do open the Startup Application list and chose the application you want to delay and click on edit. Now edit the command with a sleep option. For example if you want to set a delay of 20 sec then add the below command at the starting of the existing command.sleep 10;
So now the new command means the will start after a delay of 20 second. you could change the time of other applications in the same way.
