Impact
It bothers me. A fix would be nice
Repro Steps & Context
The Installed packages page in the Visual Studio Package Management UI can be slow to load.
Part of the reason for this slowness is HttpClientHandler's MaxConnectionsPerServer setting, which by default is 2.
Increasing this value results in a much faster load time. In the attached video, setting MaxConnectionsPerServer to 20 reduces the time taken from ~42 seconds to ~14 seconds.
max.connections.per.server.mp4
This can be further improved by changing PackageMetadataResourceV3.GetMetadataAsync to make its API requests concurrently. In the attached video, the time taken is further reduced to ~5 seconds.
