Ideally we'd like to have PR tests run in <30m so people can actually react to the results multiple times in a business day. Once they start to take 1h, 2h, etc we really limit throughput (as does flakiness)

We've made a bunch of improvements here over the years and recently, but we still have some pretty slow required jobs at the moment.

Recent Improvements:

• bump kubernetes unit test jobs on master branch to use whole machine test-infra#34476 (got unit tests under 30m )
• speed up e2e-gce test-infra#34493 (should slash the ~20m we spend building instead of testing)
• pull-kubernetes-integration: split into Go and cmd testing test-infra#34387 (split off ~15m of make test-cmd from make test-integration in CI to two jobs)
• stop overriding max concurrency in CI, let automax procs handle it #130758 (should bring integration tests down from >1h to ~35m after the split)
• Assorted improvements to integration tests in integration tests are painfully slow #126202

TODO:

• pull-kubernetes-verify is SLOW, see also verify: conformance-yaml, e2e-images, should not take >3m #130756
• we can probably still shave some time off the integration tests
• confirm e2e-GCE improvements
