The minimum number of free pages of memory seen was 133. The value of lotsfree was 535 pages and the maximum value of gpgslim seen was 503 pages. The value of desfree was 133. The minimum number of free pages was less than the peak of gpgslim, confirming that the system was under some amount of memory pressure.

The following graph illustrates the fact that freemem was usually between the values of lotsfree and gpgslim, indicating that this system would occasionally need to free up some memory, but memory pressure was generally light. The fact that gpgslim was not constant is an indication that the system could benefit from more memory.

The value of gpgslim was regularly greater than the value of desfree. This shows that vhand was active and vhand activity is confirmed by the fact that it used 4 seconds of CPU time. The vhand daemon is responsible for freeing pages of memory in the buffer cache and the value of gpgslim is recalculated whenever vhand runs and freemem equals zero. Vhand activity and changes in the value of gpgslim are generally seen on systems that could benefit from additional memory.
