I have setup virtualmin on a new debian 11 server and after setting all domains up I realized, that the system is not using any virtual memory.
Is there a reason for ? Since the hardware setup of the new server is pretty similar to the old one I wonder what is the reason to have the usage of Virtual memory steady at 0 …
Absolutely but that is the first time I see that debian isn’t touching the swap tho … thought at first sight its a virtualmin thing but saw now, its the overall swap and its free.
Seems to be a Debian 11 thing tho, used Debian 9 a week ago, was a swap hell compared to this
maybe swappiness value has changed, maybe daemons don’t use so much swap in newer versions, maybe other things too…
with ssd disks it’s not so bad using swap, but with hdds, high swap usage can cause a very high load on server… (slower responses - read/writes)
