Difference in load configuration for watch delay tests show how huge the impact is. Even with random write scheduler grpc under http server can only handle 500 KB with 2 seconds delay. On the other hand, separate grpc server easily hits 10, 100 or even 1000 MB within 100 miliseconds. Priority write scheduler that was used in most previous releases is far worse than random one. Tests configured to only 5 MB to avoid flakes and taking too long to fill etcd. Signed-off-by: Marek Siarkowicz <siarkowicz@google.com>
