             Summary: .NET: high cpu usage when using OpenCensus module
                 Key: IGNITE-17566
                 URL: https://issues.apache.org/jira/browse/IGNITE-17566
             Project: Ignite
          Issue Type: Bug
          Components: platforms
    Affects Versions: 2.13
         Environment: Apache Ignite: v2.13.0

JDK: v1.11

.NET Core: v6.0

2 instances of 2vCPU and 6GB each
            Reporter: Danut Radoaica
         Attachments: apache ignite prod 2022-08-22 183303.png

At every 60seconds (the export period) we have an aprox. 0.5vCPU spike.

I attached an image with CPU/RAM levels.
