I have done a server set up in the Amazon . The servoy version 6.0.6 , OS - Windows 64 bit . The java version is 1.7.0._04 and 64 bit . I am accessing the web client solution . The application runs fast most of the times . But some times the application hungs at all the places . Why there is this inconsistency in the performance ? . What is the reason for this difference ? .
That is a tough question to answer without more information. Are you doing any monitoring on the server?
How much ram does it use when these slowdowns occur. Are there any database locks when this happens ? Do you see slow queries in the statistics page. How many clients are open. How big is your connection pool for the database (and how much is used), etc.
