ASYNC_NETWORK_IO issue

I am running a Stored procedure which select from a table and returns approx 800000 records. When calling from any client machine it takes long time to return the result (90 sec). It waits for ASYNC_NETWORK_IO which is pushing the result to client. If select statement is used with TOP operator to return less number of records it executes faster. When calling from the server the stored proc returns data in 13 sec with all records. In another machine of identical HW and configuration this problem is not there. Can anyone help how to improve ASYNC_NETWORK_IO issue?

SQL-2005 SP1 64 bit Standard on Active/Passive cluster
Windows -2003 Ent.

Thanks

Hi, Ashis,

Did you encounter this problem during replication? If not, can you please post your question to "SQL Server Database Engine " or "Transact SQL" alias? That way, you have a better chance of getting an answer.

Thanks,
