It appears that whenever an I/O intensive process kicks off, kswapd, kjournald, kreclaimd, raid5d, and bdflush start hogging CPU time and in turn slowing other active processes down. I realize that these daemons are necessary, but they seem to be unusually active lately.
I was hoping you experts would be shed some light on my situation to gain back the performance.
- RedHat 7.3
- 2.4 SMP packaged with the install
