Hi @chuck-buford_5284 ,
Thanks for letting me know; can you let me know what queries were deadlocked? We shouldn't see any deadlock, but I guess it'd be possible for SELECT * FROM [NuGetFeedPackageVersions_Extended] to deadlock on itself depending on the query plan sql server uses.
There are a few other things we can try, but we can't repro this at all, even in a test lab that's just hammering the database. Are you using SQL Server Express (i.e. what Inedo Hub installs by default)? It should work the same of course...
Caching packages use that "CreatePackage method", so it's basically the same thing as installing a package I suppose.
Cheers,
Alana
