Description
__Steps to reproduce:__
We are seeing multiple users reporting large spikes in CPU and memory consumption since 2.5.

__Expected behavior:__
InfluxDB should not be grabbing excessive amounts of CPU and memory on relatively low workloads.
__Actual behavior:__
InfluxDB performance should remain stable.
__Environment info:__
Seen on multiple deployments:
- AWS EC2 instance of type R5a.8xlarge.
- 60% CPU load on my 8 core ryzen 3700. Dashboard
