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

Comece reproduzindo a comparação entre TestSlow usando repo.Commits.QueryBy(path) e git log --follow --oneline -- <file> em um repositório grande. Use a visualização do profiler e os tempos reportados para localizar onde QueryBy gasta seu tempo. Considera-se concluído quando o tempo de execução no repositório grande for reduzido para se aproximar do comando git comparável, preservando as entradas de commit retornadas.
