IQFEED and Matlab too slow

IQFEED and matlab are too slow. When I use any other charting software it works fine, Matlab seems the problem. I am using R2016a. Any idea why this could be a problem?

For anyone interested, the IQML (IQFeed-Matlab) connector was specifically designed for top performance, including parallel and asynchronous (background) queries.

Here is a simple usage example that uses parallel history queries for 4 symbols (requires Parallel Computing Toolbox):

data = IQML('history', 'symbol','IBM,AAPL,MSFT,GOOG', 'UseParallel',true);
