Question

My Application spend too many time on Wait method

Environment:

• .Net 4.0
• App Platform x86
• Console app
• win server 2008 (x64)

I’ve checked performance by dottrace

Wait is marked by SecuritySafeCriticalAttribute

Please note on Win7 (x64) all works fine. I found nothing, any suggestions are welcome.

Task Processing

private readonly BlockingCollection<TTask> _queue = new BlockingCollection<TTask>();
private Thread _workThread;

public void ProcessTask(TTask task)
{
    _queue.Add(task);
}

private void ProcessTask()
{
    while (_isRun)
    {
        try
        {
            TTask task = _queue.Take();
            if (task.IsNull())
            {
                continue;
            }
            _log.DebugFormat("Sending task: {0}", task);
            DoProcessMessage(task);
        }
        catch (Exception ex)
        {
            _log.Error(ex);
        }
    }
}

Solved

Looks like dottrace show the weather. I’ve checked performance by ANTS Performance Profiler and fixed the issue. Problem was in sql request thru NHibernate
