Red Hat 8.0 system becomes sluggish
After a few days of up time my redhat 8.0 system running the latest kernel becomes very sluggish. The screen redraws very slowly the mouse is choppy programs take a long time to launch and sometimes do perform correctly. The only program that I have open continuously is XCHAT 2.01 running a python script. I monitor top regularly which indicates 90-99 percent CPU idle throughout the day my memory is almost entirely used however I notice a lot of disk usage when accessing programs as if virtual memory is taking a hit. Is there a way to increase the efficiency of the memory without rebooting? Or any other ways to increase the performance?
