I had Asus A555L series laptop whose configurations are as follows:

Processor: Intel® Core™ i3-5010U CPU @ 2.10GHz × 4

RAM: 4GiB SODIMM DDR3 Synchronous 1600 MHz

Hard-disk: 1TB ATA disk

I am running Windows 10 and Ubuntu 16.04 LTS as dual boot. Every time I boot into Ubuntu OS, I had to mount my both HDD partitions (I have two HDD partitions other than that of where Windows 10 OS is installed). As I am a developer, when I run few softwares like Eclipse, VS Code, and Chrome, laptop starts lagging. I have checked disk, CPU, and IO usage using top and iotop commands and found that sometimes IO increases to nearby 80-90% where as sometimes CPU reaches 80-90%. But had never seen RAM usage more than 10%. What makes IO and CPU usage increase to such high levels? How to stop my laptop from lagging?


Try turning off fast boot options from Windows power options. Then you don't have to mount your partitions again.
