1. 配置使用多个scheduler

https://kubernetes.io/docs/tasks/administer-cluster/configure-multiple-schedulers/

2. 优化

• Equivalence class based scheduling in Kubernetes

  https://github.com/kubernetes/community/blob/master/contributors/design-proposals/scheduling/scheduler-equivalence-class.md

3. 性能测试

性能测试命令：

a. Scheduler Performance Test

# In Kubernetes root path
make generated_files

cd test/integration/scheduler_perf
./test-performance.sh

b. make

make test-integration WHAT=./test/integration/scheduler_perf GOFLAGS="-v=1" KUBE_TEST_VMODULE="''" KUBE_TEST_ARGS="-run=xxx -bench=BenchmarkScheduling"

c. Scheduler Benchmarking

4. 其他调度器

• Nomad
