This node usage is at 122%
Why is there a limit on the node?
BirdsiteLIVE rely on the Twitter API to provide high quality content. This API has limitations and therefore limits node capacity.
What happen when the node is saturated?
When the saturation rate goes above 100% the node will no longer update all accounts every 15 minutes and instead will reduce the pooling rate to stay under the API limits, the more saturated a node is the less efficient it will be.
The software doesn't scale, and it's by design.
How can I reduce the node's saturation?
If you're not on your own node, be reasonable and don't follow too much accounts. And if you can, host your own node. BirdsiteLIVE doesn't require a lot of resources to work and therefore is really cheap to self-host.
