I Have recently dual booted Ubuntu on my old windows laptop. But after installation Ubuntu feels very slow. It takes much time to boot and reach to login screen. Opening basic Applications like file manager, Browser and all the other apps takes too much time. Earlier when I was using Windows 10 on the same machine it never felt slow in booting and performing basic operations like surfing web opening applications.
Machine specifications :
processor = Intel Pentium N3710 Ram = DDR3 4GB storage = 512 (HDD)
