I can replicate slow extraction locally (although faster than pipelines). what works even faster is using 7zip which may actually be pre-installed on pipelines:
"C:\Program Files\7-Zip\7z.exe" e -y -o"C:\dev\download_sf_boost" "C:\dev\download_sf_boost\boost_1_79_0.zip"
PowerShell which extracts Boost
boost_1_79_0.zip
(187MB) is extremely slow. -> ~18minutes on the pipelines. https://github.com/microsoft/sql-server-language-extensions/blob/fc6a854a0d87dfb6a3c71194f67097792da32299/language-extensions/python/build/windows/restore-packages.cmd#L55I can replicate slow extraction locally (although faster than pipelines). what works even faster is using 7zip which may actually be pre-installed on pipelines:
This works in a fraction of the time 1-2 minutes.
