Faster hyper-v container startup time
JensNordenbro opened this issue · 3 comments
Today on Windows, docker container startup (HyperV-containers) seems to be dependent upon size of docker image.
This is not the case in Linux (not noticable at least).
Example on my machines:
docker run -it mcr.microsoft.com/dotnet/sdk:8.0.203-nanoserver-1809 -> ca 4 sec startup
docker run -it mcr.microsoft.com/dotnet/sdk:8.0.203-windowsservercore-ltsc2019 -> ca 15s startup.
This needs to be mitigated !
Hey @JensNordenbro, are these startup times the first container startup times? If not, how long do the n+1 containers take? The first container startup usually takes extra time.
Running:
1>docker run -it mcr.microsoft.com/dotnet/sdk:8.0.203-nanoserver-1809 cmd.exe /c:exit
takes 3 seconds on my machine , similar result all times.
2>docker run -it mcr.microsoft.com/dotnet/sdk:8.0.203-windowsservercore-ltsc2019 cmd.exe /c:exit
takes 19s on my machine , similar result all times.
3>docker run -it mcr.microsoft.com/dotnet/sdk:8.0.203-windowsservercore-ltsc2019 cmd.exe /c:exit
takes 5s on my machine , similar result all times.
