Is there a good Linux diagnotic tool to check laptop slowness?

in flag

I bought a Samsung laptop (NP770Z7E) with Windows 10 but it was running too slow. So I installed a Linux OS but it still slow. It seems some problem with memory but I would to see if some tool can test and report the problem.

What is your exact model of laptop? If the preinstalled Windows was also slow, I strongly advise you to take it back where you bought it for a repair or replace, most reputable stores will give warranty.

Thanks for your advice @MarkKirby. But I bought it when I was in Europe. I no longer have a warranty.

OK you certainly meet minimum specs. If you think it is a memory issue try `sudo apt install memtester` To run it use `sudo memtester size iterations` where size is the amount of ram you have or wish to test and iterations is the number of times you wish the test to run (1 is fine).

The `hardinfo` tool may give some basic information about your system. There are some CPU benchmarks there. However, you should check also `syslog` for hardware / software problems.

Take a look at [MemTest86](https://www.memtest86.com/). It might do what you want

Are you using an HDD or an SSD? There's a huge difference in performance. If you are still having trouble, I would suggest upgrading to a Solid State Drive.

Ok. I'll try to do all suggestions soon. Thank you all for your time.

You've provided no OS & release details which is where I'd start. Some OSes & releases do benefit from tweaking post install; but you need to start here by providing release details (Linux is the kernel all GNU/Linux use and is not very specific, after all Android uses the linux kernel too).

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
