Also, there are no other resources consuming memory on our server. Then, open an “xterm” window and get the result of free -mh command. For single application, the size of Qt looks bloated, but from the viewpoint of a DE, the cost can be amortized so we can still have a descent environment that has reasonable resource usage while using a nice C++ toolkit.

Well, LXDE and LXQt all have the file manager daemon running as well so that's a fair comparison. (For openbox, which brings no file manager, the gtk2 version of pcmanfm is used) The memory usage of LXQt is quite similar to the original LXDE (gtk2) while many new features are added. What really matters is how you use them. 120 MB vs 300 MB can make a difference. It consists of many small individual components like a panel program, session manager, hotkey daemon and a few more. LXQt 0.9, Qt 5.3, and KF5 packages are taken from Siduction; Running in Virtualbox 4.3.20; RAM: 512 MB; CPU core: 1; Screen resolution: 1024×768; Measurement: Open xterm, and type `free -mh` (cache and buffer are excluded) Memory usage after cold boot: LXQt 0.9: 118 MiB; LXDE: 98 MiB; XFCE: 107 MiB; plain Openbox (without running any apps): 70 MiB Borrowed some concepts from economics. Active 3 years, 9 months ago. They were putting full windows OS on donated machines. Well, comparison of 150 vs 300 MB sounds unimportant to me, when my typical web browser instance eats 1-2GB of RAM. For email. I've encountered no graphic problem after the upgrade. So, if that was to get deducted from Xfce's overall memory usage (in the event the daemon was not turned) that reduces the memory footprint down to about 120/124 vs LXQT's 117/120, which is negligible at best.

And, on another note, my home computer boots up faster when it doesn't have to extract lots of DE code from the disk to the RAM. Most modern desktop computers are shipped with enough RAM nowadays, but this is not the case with smaller devices such as Raspberry Pi. So PcManFM was used. Comparison of ease of use and stability. The following sample code uses the GetProcessMemoryInfo function to obtain information about the memory usage … It includes essential applications and services for daily use, including office suite, PDF reader, image editor and multimedia players. You'll be able to view how much of your computer's RAM is being used in graph format near the top of the page, or by looking at the number beneath the "In use (Compressed)" heading.
