Throttle Messages Per Second

Question

I am attempting to throttle the amount of messages I send to a SMPP SMC(server). I need to throttle them so the SMC does not throttle and drop my messages.

This is what I have tried:

double _client.SendSpeedLimit = 20;
if (Math.Abs(_client.SendSpeedLimit) > 1E-6 && _lastSubmit != DateTime.MinValue)
{
    check submit speed and wait for next time
    double elapsed = (DateTime.Now - _lastSubmit).TotalMilliseconds;
    if (elapsed < 1000f / _client.SendSpeedLimit)
    {
        int interval = Convert.ToInt32((1000f / _client.SendSpeedLimit) - elapsed);
        Thread.Sleep(interval);         
    }
}

and...

int left = (int)(start.AddSeconds(1.0 / (double)_client.SendSpeedLimit) - DateTime.UtcNow).TotalMilliseconds;
if (left > 0)
{
    MobileDAL.InsertError(Settings.Default.MobileConnectionString, "Throttled: " + _clientFriendlyName, "", _AccountID);
    Console.WriteLine("Throttled: " + _clientFriendlyName, "", _AccountID);
    while (left > 0)
    {
        Thread.Sleep(10);
        left = left - 10;
    }
    start = DateTime.UtcNow;
}

But they dont seem to work as expected because I still get throttled by the service provider(SMC). Is there something wrong with the code? Could someone offer points of improvement?

Have you tried logging between each interval to verify you are throttling to the appropriate speed? — Daniel Kelley, Jun 26 '14 at 07:34
Yes I have, the methods do seem to log. However we are talking anything between 5-100 as a SendSpeedLimit(messages per second) — BossRoss, Jun 26 '14 at 07:38
