1# Linkerd Stress Testing
2
3The `air-fryer` pallet makes use of Buoyant's [strest-grpc](https://github.com/BuoyantIO/strest-grpc) tool used to stress test the linkerd solution.
4We have named this pallet `air-fryer` to accompany the `slow-cooker` solution used for load testing.
5
6The pallet installs a gRPC server and a gRPC client pod on each node of the cluster.
7The `air-fryer` client will make 2000 requests per second to the gRPC servers.
8This will run until the client pod is removed.

10## Results
11
12Every ten seconds the number of bytes, number of good/bad requests, request latency and jitter will be recorded by the client.
13To see the output run:
14
15```
16k logs -n air-fryer air-fryer-client-<UUID> air-fryer-client
17```

19Please see the example output below:

22# sending 2000 GET req/s
23# time iter bytes good/bad dur latency min [p95 p99] max jitter p95 p99
