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?

@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.
