I bought about 6 months ago a good laptop (Lenovo ThinkPad E550 : Intel Core i5-5200U, 8 GO DDR3, AMD Radeon R7 M260) and installed Debian Jessie with Gnome 3 (no unity) on it. The system worked fine in the beginning, but more recently I'm having performance problems regularly.

It seems like there is a lot of memory used, and the laptop begin to slow over time until it's very near the freeze. Just now, I've boot up the laptop and launch Chrome + Webstorm and it's already 3.7 Go of memory used.

It's very annoying because I'm working as a web developer, and I need to launch VirtualBox in top of this. And often it slows really hard the system, where there should not. I think my hardware is more than sufficient for running IDE, browser and virtualbox

Do you have any idea?

P.S. : Here is a copy of ps -au command just now, maybe it helps:

htop result

  • Install and run the htop command, it'll tell you which process is clogging the memory. – dr01 May 27 '16 at 12:39
  • I added it to the question, looks like chrome is eating a lot... – Jérémy Dutheil May 30 '16 at 7:48
  • Please add to the post, How many tabs in chrome, and why virtualbox? Do you have an email client running too? How big the mailbox? – Rui F Ribeiro May 30 '16 at 8:08
  • No tabs in Chrome, it's just after launch ; virtualbox is needed for photoshop, anyway it shouldn't be a problem to run 3 softwares with my hardware.. I don't have email client – Jérémy Dutheil May 30 '16 at 19:33
  • Does the slowdown happen if chrome is run without webstorm? – agc Jun 1 '16 at 2:26
