repo.Commits.QueryBy(filename) slow on large repos

Reproduction steps

1): Clone a large repo
2): run this function on that repo with some random file:

public IEnumerable<string> TestSlow(string filename)
{
    using (var repo = new Repository(repoRoot))
    {
        string path = filename.Substring(repoRoot.Length + 1).Replace("\\", "/");
        foreach (LogEntry entry in repo.Commits.QueryBy(path))
        {
            yield return entry.Commit.Author.ToString();
        }
    }
}

3. run this command on the same file: "git log --follow --oneline -- "

Expected behavior

I expect similar time to be taken by TestSlow and the git log command above

Actual behavior

The git log command finishes in about 1.6 ms on my repo
The TestSlow command takes about 70 seconds.

Here is what I see in my profiler:

Version of LibGit2Sharp (release number or SHA1)

0.27.0-preview-0017
0.26.1
0.24.1

Operating system(s) tested; .NET runtime tested

.NET Framework 4.7.2 on Windows 10

Empieza reproduciendo la comparación entre TestSlow usando repo.Commits.QueryBy(path) y git log --follow --oneline -- <file> en un repositorio grande. Usa la vista del profiler y los tiempos reportados para localizar dónde emplea su tiempo QueryBy. Se considera terminado cuando se reduzca el tiempo de ejecución en el repositorio grande hasta aproximarlo al del comando git comparable, preservando las entradas de commit devueltas.
