Waiting Too Long While Fetching 100 Rows Data from Database

Member for

I am relatively a new Knime user. It is an excellent product. As soon as possible, when I learn Java programming I will make contributions to the platform. 

For now, I have a problem. I am connected to Oracle database. When ı first open my workflow, I can run a table connection node. But after that, when I want to  connect different database tables, I am waiting too long. When I want to fetch only 100 rows from database I am waiting too long. My memory preference is "keep only small size"... Also when I want to write table to database, I am waiting too long and at last, it does not writes to table. Node says that: "opening database connection"...


How can I solve this problem? 

So many thanks...
