[OpenIndiana-discuss] Question about System Monitor

[russell]

Hi,

I am running Hipster 2021.04 with illumos-3f770aab81 and running System 
Monitor 1.24.2.
System monitor is reporting Memory utilisation of 17.5GiB (27.5%) of 
63.9GiB, however it is reporting 115.7MiB (0.7%) of 15.9GiB of swap it 
being used.
I have always thought that swapping occurred when there is insufficient 
memory for an application so another application or pages of an 
application could be swapped to disk to free RAM.
Given that there at least 32GB of RAM free, surely it would not need to 
page.

While it is only around 100MB can I tweak the system to avoid paging 
when there is so much ram?

TIA
