Mysql performance

I am testing MySQL as a replacement for SQL Server and I am running into something really weird. I am testing for both inserts and reads and am maxing out 50 requests per second anyway.

My test table looks like this:

DROP TABLE IF EXISTS `webanalytics`.`test`;
CREATE TABLE  `webanalytics`.`test` (
    `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
    `name` varchar(45) NOT NULL,
    PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1001 DEFAULT CHARSET=utf8;

      

        
        
        
      

    

And my C # test program looks like this:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using MySql.Data.MySqlClient;
using System.Diagnostics;

namespace ConsoleApplication1
{
    class Program
    {
        const int QUERY_COUNT = 1000;
        const string CONNECTION_STRING = "server=localhost;database=WebAnalytics;uid=root;pwd=root";

        static void Main(string[] args)
        {
            using (var db = new MySqlConnection(CONNECTION_STRING))
            {
                db.Open();
                using (var cmd = db.CreateCommand())
                {
                    cmd.CommandText = "insert into Test(Name) values (?Name);";
                    cmd.Parameters.AddWithValue("?Name", "");

                    var timer = new Stopwatch();
                    timer.Start();

                    for (var i = 0; i < QUERY_COUNT; i++)
                    {
                        cmd.Parameters["?Name"].Value = "Test" + i;
                        cmd.ExecuteNonQuery();
                    }

                    timer.Stop();
                    var rate = QUERY_COUNT / (timer.ElapsedMilliseconds / 1000);
                    Console.WriteLine("Query rate: {0}/s", rate);
                }
            }
        }
    }

}

      

        
        
        
      

    

This seems to be a pretty basic test case. When installing for MySQL, I run the default 32-bit OLTP server standard setup, although I had to tweak the buffer pool for innodb down from 2G to 1G. I don't understand where the bottleneck is. Is the MySQL data connector buggy? The dottrace profile session shows the following:

I don't know the inner details of the MySQL connector, but the calls to mysqldatareader.nextresult are confusing me. Why does it read when I do an insert?
