UbuntuMATE 20.04 LTS and BFS Scheduler

  • 772

Can anybody tell me if UbuntuMATE has already incorporated the BFS Scheduler patch components highly praised by Linus in the article here ?

I realize that reference is from 2010, but I am trying to understand why my Desktop is sluggish, when I am not doing any "heavy" work (no compiling, no typesetting, no database, no spreadsheets, no dashboards). I only have my browser with 2 or 3 Gvim windows, a console window, 2 Caja file cabinet open and that is all.

I have 4G of RAM. As for swap,

root@OasisMega1:/DB001_F2# swapon
NAME      TYPE      SIZE USED PRIO
/dev/sdc1 partition   2G 2.3M    1

I want to underline that the swap is on a physically different device, which is not my system or boot disk.

I've seen references to changes to swappiness but anything I've tried has made things worse, so I put the value back to the Distro default.

Any suggestions?
