How to handle WCF in push and pull the heavy data from SQL

Question

hi,
I have question which is prescribed in bullet points

• In my Asp application I need to push 1000 records at at a time   to Sql via WCF service in form of Class object
• The Entity object communication is purely class object and serelizable
• The service reference configuration is Array
• I configured web config file  at client UI side by increasing array length,readerquotas,stream reader at max level 20k
• It able to send 50 records at a time to sql via WCF with out time bound error .
• The binding i implemented is BasicHttpBinding .
• Less than or equal to 50 records it fine to push the records 50 through wcf with Array configuration
• But in future i need to push more than 10K i am surprize WCF failing with above scenerio kindly help me
