[🐛 Bug]: [dotnet] Performance degradation in case of parallel tests

[nvborisenko]

Description

In the latest v4.35 parallel tests execution is significantly depredated. This is definitely related to driver service process output redirection.

Reproducible Code

Parallel.For(0, 10, i =>
{
    using var driver = new ChromeDriver();
});

ℹ️ Last known working version: 4.34.0

More details:

for (int i = 0; i < 10; i++)
{
    var sw = Stopwatch.StartNew();

    Parallel.For(0, 10, _ =>
    {
        using var driver = new ChromeDriver();
    });

    Console.WriteLine(sw.Elapsed);
}
