Initial performance when opening or querying NuGet feed from Visual Studio Package Manager

ygeelen-tb

It takes many seconds to browse or search through a ProGet NuGet feed from Visual Studio (both proxy feeds to nuget.org and private feeds).
Sometimes we even need to cancel the search operation and retry because we get no results.

I already tried some things which seem to be an improvement:

     Configure the IIS application pool StartMode to AlwaysRunning

     Configure the IIS website to Preload Enabled = True

     Check the ProGet cleanup interval: for all feeds this is a frequency of 1 day between 2:00 and 7:00. I read that ProGet reindexes feeds whenever cleanup occurs and that this slows down a lot; however nobody works between those hours.

     Configure the IIS application pool Recycling Regular Time Interval. This has a default value of 1740 minutes or 29 hours. I have set this to 0.

     Configure the IIS application pool Idle Time-Out: it is set to 10 minutes by default. I have set the Idle Time-Out to 0 (=never let the IIS worker process shut down).

     Configure the IIS application pool Specific Times: 01:00:00.

Are there any other measurements I should take or do you have more advice?

I recently upgraded to ProGet 3.6.1 (Build 6) and I'm using IIS hosting and a SQL Server Express database.

Product: ProGet
Version: 3.6.1

If ProGet is idle for a while, then it will shut down to conserve system resources... however, you've already identified how to fix it (Idle Time-Out = 0). That will only effect the first request, however.

Otherwise, the slowness is coming from your connector to NuGet.org; this is a known issue (nuget.org's poor responsiveness), and one we plan to rectify at some point in the future by creating a local index of nuget.org (see the roadmap.

I've read that NuGet's architecture is being redesigned for version 3.0, which should also improve the performance.
