You can use the free command to display the amount of free and used memory (RAM) in the system. In this tutorial, I'll show you how you can achieve the following in the terminal:Ĭheck the total RAM size and the free RAM You may even want to check the kind of RAM it is (DDR1 or DDR2). My computer is becoming increasingly difficult to use.As someone who manages Ubuntu servers, you'll need to know how much RAM your system has, and how much of the RAM is free to use. CPU usage is not very high either - hitting a max of 22% occasionally.Īs mentioned before, I'm running Ubuntu 20.04.3 LTS. What are these and why are they using up so much memory? The system freezes and behaves very slowly during use. I dont understand this because according to htop, Chrome is using only 2% or so of memory.Ģ-4% should not be hogging up the entire memory, so I ran free -m and found out that buff/cache and shared usage is very high - 8.8GB and 7.2GB respectively. Java, MySQL, Apache, I've read are usually the culprits of high RAM usage, but Java isn't even running, and the other listed processes are barely using 0.1% of RAM.Īnother thing I've noticed is, upon closing Chrome, the memory usage instantly drops from 10.1GB to only 1.7-2GB of usage. I've run htop and top but they don't return useful information, ie it shows Chrome and Discord using the most amount of RAM - just 2-4% each. I've tried to follow the other suggestions posted on this forum about similar issues. The RAM fills up over time and reaches dangerously high levels of usage, even when I am using only 2 applications. Ubuntu 20.04.3 LTS is using a lot of memory, (10.1GB out of 12GB of RAM).
