Trying to compare grpc to minimal api performence- minimal much faster, Logic probably rotten

So i got this grpc client that streams data from a csv to a console and just prints it,
in 1 minute it can do about 1.5mil records.
On the other hand i got this minimal api, Now here begins the problem
Im guessing I need to use httpclient to make the call inorder to compare?
Because before i had this:

var client = new HttpClient()
; await foreach (var line in MakeHttpCall())
{
    Console.WriteLine(line);
}

var client = new HttpClient()
; await foreach (var line in MakeHttpCall())
{
    Console.WriteLine(line);
}

And this was twice as fast , 3 million records in a minute then i figured out im testing it wrong,
However how do i use a client and what methode i need to invoke in the foreach?

  async IAsyncEnumerable<string> MakeHttpCall()
{
    var watch = System.Diagnostics.Stopwatch.StartNew();
    int Count = 0;

    using (var reader = new StreamReader(@"C:\Users\kosta\source\repos\gRPCDemoUsingNET6\gRPCDemoUsingNET6\Data\sales_records.csv"))
    {
        while (watch.Elapsed < TimeSpan.FromSeconds(60) && !reader.EndOfStream)
        {
            var line = reader.ReadLine();
            var values = line.Split(';');
            yield return line;
            Count++;
        }

    }
    watch.Stop();
    Console.WriteLine($"Stream ended: Total Records:{Count.ToString()} in {watch.Elapsed.TotalMinutes} minutes and {watch.Elapsed.TotalSeconds} seconds.");
}

  async IAsyncEnumerable<string> MakeHttpCall()
{
    var watch = System.Diagnostics.Stopwatch.StartNew();
    int Count = 0;

    using (var reader = new StreamReader(@"C:\Users\kosta\source\repos\gRPCDemoUsingNET6\gRPCDemoUsingNET6\Data\sales_records.csv"))
    {
        while (watch.Elapsed < TimeSpan.FromSeconds(60) && !reader.EndOfStream)
        {
            var line = reader.ReadLine();
            var values = line.Split(';');
            yield return line;
            Count++;
        }

    }
    watch.Stop();
    Console.WriteLine($"Stream ended: Total Records:{Count.ToString()} in {watch.Elapsed.TotalMinutes} minutes and {watch.Elapsed.TotalSeconds} seconds.");
}

How do i procced? obviously im doing smth/multiple things wrong.
If i try to do smth like this

 await foreach (var line in client.GetAsync(""))

 await foreach (var line in client.GetAsync(""))

I get a "does not contain extension defenition for getasyncenumarator
