Hi,
I am experimentally minimizing the footprint of a SLES10 WebSphere 7 instance
and seeing the following.
Swap is to v-disk.
top:
Tasks: 120 total, 3 running, 117 sleeping, 0 stopped, 0 zombie
Cpu(s): 5.3%us, 0.3%sy, 0.0%ni, 94.0%id, 0.3%wa, 0.0%hi, 0.0%si, 0.0%st
Mem: 2050776k total, 2041236k used, 9540k free, 120320k buffers
Swap: 849964k total, 819676k used, 30288k free, 431684k cached
rmf:
Total memory size 2002MB Swap space size 830MB
Total memory used 1507MB % Swap space used 96.4%
Used for buffer 117MB Swap-in rate 1.233/s
Used for shared 0MB Swap-out rate 0/s
Used for cache 422MB Page-in rate 4.933/s
Total free memory 7MB Page-out rate 35.888/s
The cache number looks interesting because it remains large while swap space is
being used up. This particular
instance has been up for 30+ days, so maybe there is incremental swap space
saturation over time?
