No evidence of an overall memory shortage was seen in the following statistics: The average number of kernel threads waiting to be paged in (swpq-sz) was 1.80. The average number of kernel threads waiting to be paged in (swpq-sz) peaked at 1.8 from 11:20:00 to 11:40:00. Peak resource utilization statistics can be used to help understand performance problems. If performance was worst when the number of kernel threads waiting to be paged in was at its peak, then a shortage of physical memory may be performance bottleneck.
The average number of page replacement cycles per second (cycle/s) was 0.00. If values greater than zero had been seen, a memory shortage might exist. Data from the cycle/s column does not indicate a lack of physical memory. No graph was generated for page replacement cycle data because no page replacement cycles were seen in the sar -r report. There was no indication of swapped out processes in the ps -elf data. |
