large consume of memory in 5.82.2

[robyt]

Hi, i've upgraded to 5.82.82 and i see a general slowdown
i'm entering via ssh in vm and i see this:

xoa@xoa:~$ free -h
              total        used        free      shared  buff/cache   available
Mem:          1.9Gi       1.5Gi        71Mi       1.0Mi       407Mi       325Mi
Swap:         2.0Gi       894Mi       1.1Gi

root     58755  4.2 12.1 11609064 245252 ?     Ssl  08:43   8:22 node /usr/local/bin/xo-server

11gb of virtual memory...
it's necessary to reboot the vm with this upgrade?
Or is a sw problem?

It's not a problem to have a high virtual memory usage. You can probably get more perf if you raise XOA available RAM.

How many hosts are you managing with this XOA?

[robyt]

@olivierlambert ~30 hosts
Now i've assigned 4gb of ram, the memory is

[14:20 24] xoa@xoa:~$ free -h
              total        used        free      shared  buff/cache   available
Mem:          3.8Gi       1.7Gi       119Mi       3.0Mi       2.0Gi       2.0Gi
Swap:         2.0Gi        76Mi       1.9Gi

Before the upgrade xoa is fast and reactive, now (with 2gb of ram) is very slow (the vm is the same)

[olivierlambert]

And now with 4GiB RAM, is it better? 2GiB is too tight for 30 hosts.

[robyt]

@olivierlambert no problem, i add some memory to vm.
The number of vCPUs is relevant?

[olivierlambert]

Depends on the load, mostly when doing backups, if you backup 20+ VMs, 4vCPUs is better.
