Logparser and execution speed

Hi,

I have c# service application which parse exchange message tracking logs. I'm confused about application speed. 10MB file logparser processedapproximately in 2 minutes. When I execute identical query in  logparser command window processing are 3 sec.

There is my code:

ILogRecordset LogList = null; 
ILogRecord LogRecord = null; 
LogQueryClassClass LogWorker = new LogQueryClassClass(); 
COMCSVInputContextClassClass LogParserInput = new COMCSVInputContextClassClass();
LogList = LogWorker.Execute(String.Format("SELECT * FROM '{0}'", MessageTrackingLogsPath, LogParserInput);
for (; !LogList.atEnd(); LogList.moveNext())
{
LogRecord = LogList.getRecord();
}
