High CPU usage when acceding http://{proget-server}/nuget/nuget/Packages

[Guest]

Hi,

Everytime a user access this url http://{proget-server}/nuget/nuget/Packages , the IIS process (w3wsp.exe) jumps to the roof taking all the CPU of the machine. The RAM is also rising.

This cause our nuget feeds to stop working and the page at that address then display :

Server Error

502 - Web server received an invalid response while acting as a gateway or proxy server.

There is a problem with the page you are looking for, and it cannot be displayed. When the Web server (while acting as a gateway or proxy) contacted the upstream content server, it received an invalid response from the content server.

Our host have 8 GB of RAM and 4 cores. We have over 2000 nuget packages. We were wondering if this is an issue or just need more ressources to be able to list all those nuget packages. Please advise.
Thank you

Assuming you don't any server misconfiguration or SQL Server latency issues, then the biggest performance bottleneck tends to be the network.

Each client/user will make dozens or hundreds of simultaneous requests, often using machines more powerful than the server, and these requests can be expensive... particularly if you're using connectors... because they have to be forwarded to another server. These requests "pile up" and eventually, the underlying infrastructure can't handle it (IIS, network card, etc), and you start getting timeouts like that.

This is where load-balancing comes in, and is pretty important in your configuration as you add users and packages.
