Ubuntu agents have slightly higher IOPS disk performance configuration. We use install-dotnet.ps1 script for installation provided by DotNet team . The DownloadFile and Extract-Dotnet-Package functions are being slow. We will investigate how to improve performance those functions if we replace DownloadFile -> WebClient and Extract-Dotnet-Package -> 7zip

DownloadFile and Extract-Dotnet-Package are awfully slow. Like 3x slower!

                          Ubuntu agents have slightly higher IOPS disk performance configuration. We use install-dotnet.ps1 script for installation provided by DotNet team . The DownloadFile and Extract-Dotnet-Package functions are being slow. We will investigate how to improve performance those functions if we replace DownloadFile -> WebClient and Extract-Dotnet-Package -> 7zip
                          DownloadFile and Extract-Dotnet-Package are awfully slow. Like 3x slower!
