NodeNeighborLinkUpdater memory usage regression #39499
Description
Is there an existing issue for this?
- I have searched the existing issues
Version
equal or higher than v1.17.3 and lower than v1.18.0
What happened?
Memory regression is happening on main.
Since #39001 was merged, memory usage of cilium-agent increased by 3-4% in scale-tests. Most of the memory increase is coming from health-reporting:
It seems fairly excessive to report health per each node and each service backed:
cilium/pkg/node/manager/manager.go
Line 1393 in 07f37d3
Proposal:
Instead of reporting health per each backend/node, let's report health one time with number of refreshed and failed entries.
How can we reproduce the issue?
