Description Hongkai Liu 2020-02-06 18:43:29 UTC 
Running the same build on 3.11 cluster and 4.3.0 cluster.
Comparing the build time:

#430
oc get build --context build01 -n ttt
NAME                 TYPE     FROM   STATUS     STARTED             DURATION
machine-os-content   Docker          Complete   About an hour ago   1h22m0s
#311
machine.os.content.debug oc get build
NAME                 TYPE     FROM   STATUS     STARTED             DURATION
machine-os-content   Docker          Complete   About an hour ago   8m36s

Reprod. steps:

oc new-project ttt
oc apply -f ttt.is.yaml
oc apply -f machine-os-content.build.yaml


The yamls and logs are attached.

Moving to the Containers team - root issues are with buildah. Needs to be moved back to Builds when ready to be vendored in.

Assigning to Nalin.  I suspect this is related if not a duplicate to https://bugzilla.redhat.com/show_bug.cgi?id=1790525

The big offenders in the 4.3 log compared to 3.11 happen during COPY instructions, and while one of them requires 4.3 to download an image, the majority of the time we spend on that instruction happens after the builder logs that the image was successfully pulled, so I do believe this is the same problem that we see in #1790525.  The COPY implementation is getting an overhaul, but that work is still in progress, so I'm moving this to 4.5.
Comment 10 Nalin Dahyabhai 2020-03-06 19:17:40 UTC 
Taking a closer look at default-route-openshift-image-registry.apps.build01.ci.devcluster.openshift.com/test-image/pipeline@sha256:9ca3e5979408a90873226d80e4d2952715bd2a4cc9db647c9d8533c588409064, this should be fixed when #1790525's fix goes out.  It doesn't require the rework I mentioned in comment 9, which targets cases where the source uses a .dockerignore file.  Marking this as a duplicate instead.
