Hi,
I would like to understand ,how performance of proxmox can be improve in better way

1) anything we can modify swap file system
2) if I do have 10 x 2 TB disk, what will be best option to create volumes ( like LVM or Zfs ) which one is better
3) Failover ethernet card or load balancing if have 50+ vms


Thanks
Upendra
 
1) always install zram-config for compressed, memory-based swap, also try minimizing swapiness (set to 1)
2) LVM vs. ZFS depends on the layer. ZFS has a lot of features, but steeper learning curve. LVM can mirroring, but normally you have a "real" raid below, not a LVM-backed raid (although possible). Please describe what you plan to do. Do you have a hardware raid card?
3) Load balancing based on LACP or something manual? What about your hardware infrastructure? Do you have failover switches, etc.
 
If your network hardware is not capable of handling load-balanced traffic, then you cannot use active-active bonding of any kind. You have to check with the manual/spec sheet of your switch. Most managed switches should be able to handle LACP nowadays.

Are you planing on having offline migration between the nodes? Are the nodes connected in a (non-HA, non shared-storage) cluster so that you can manage all via one GUI?
 
Thanks for reply.
I am not planning for migration , there is no cluster at all.
All my servers are running as a single node however I am trying to make them optimize in performance.
