[UI] Maas gui performance is slow

[Xav Paice]

I have a maas with 24 nodes, 2 controllers (package 2.1.3+bzr5573-0ubuntu1~16.04.1).

The page load times are generally around 5-15 seconds when just clicking around, however when I go to view a particular node's details it'll take around 15-20 seconds at minimum. If I make a change to the network configuration for a node in 'ready' status, such as adding a bridge or renaming a bond, the page doesn't ack the click on 'save' for 5-10 seconds, and after that the networking section on the page doesn't get a refresh every time, leading to missing details and clicking on the wrong thing, or losing config entirely and having to repeat it.

These nodes have several nics each, connect to seven different vlans with various bonding configs, and each connection needs configuration.

The NIC comments also go for disk configuration.

If you can verify that the logs don't need any sanitation, I'll attach them too - but this is a customer site and I'd want to avoid any identification or sensitive info being available.

Hi There,

Can you please confirm whether this is still a problem with MAAS 2.2 ? MAAS 2.2 has gone extensive re-organization that considerable improves performance.

MAAS 2.2.1, which will come out soon, has further performance improvements that should make navigation in the device listing/dashboard, node listing and events page much faster, and should improve the performance overall.
