So you need figure out a way for others to repro the timings you are seeing.

Partial dockerfile where issue is experienced:
docker version:
Run with
DOCKER_BUILDKIT=1 docker build --progress=plain .For reasons I can't explain, the build becomes very slow at the ubuntu install stepLinking and byte-compiling packages for runtime python2.7...which runs/usr/bin/pycompile -V 2.7 /usr/lib/python2.7/dist-packages. Eventually, this task completes after ~120 seconds and slows again at the next pycompile step. I've let this run for almost 2 hours before killing the build.Building this dockerfile with
DOCKER_BUILDKIT=0 docker build .completes in 76 seconds.I am currently unsure why BuildKit would have much worse performance installing these packages in Ubuntu than the older docker build engine. Overall, BuildKit seems to perform better for other scenarios I've faced. If there's more information I can provide to help troubleshoot this issue, please let me know.
