SQL Developer responding slowly

Question

Hi,
I am connecting to Oracle DB from SQL Developer using remote connection through LDAP. I work with sql server management studio regularly but through sql developer this is my first time.
I find SQl developer slow compared to sql server management studio- IS this true or is it because of the remote connection.?
What steps can I take to improve its speed . Are there any tools or settings that I need to change?
I have a simple insert query into a temporary table which ran for 5 hours.The application does not stop executing after that and I need to end it from task manager. I think this is to do with the buffer size, so I need to commit data in batches to process it more speedily.Are there any settings to do to run data in batches?
Thanks for your time and help

Based on the code you posted in a later reply this does NOT appear to be a sql developer issues at all and should be posted in the SQL and PL/SQL forum.
PL/SQL
Before you post there please read the thread 'How to post a tuning request' located at
HOW TO: Post a SQL statement tuning request - template posting
That thread discusses the information that you need to provide in order for volunteers to be able to make meaningful suggestions. That information includes
1. the DDL for the tables and indexes involved
2. the row counts for the tables
3. the row counts for the query predicates
4. the execution plan for the query
5. the expected row count of the result set
Based of this code that you posted
INSERT INTO Temp
SELECT
VisitNo,
EmployeeNo,
(SELECT EmployeeNo FROM Employee e WHERE e.CaseNo = clin.CaseNo) emp,
ROW_NUMBER() OVER (ORDER BY VisitNo, CaseNo) rnum
FROM
ClinicVisit clin
ORDER BY
VisitNo,
CaseNo;the query will simply be sent by sql developer to Oracle for processing. Sql developer will play no further role until the query is actually completed. So based on this example code there is no basis at all for saying:
1. sql developer is slow
2. the application does not stop executing - please clarify what you mean by 'application' and by 'does not stop'
3. I think this is to do with the buffer size
4. I need to commit data in batches to process it more speedily
5. the remote connection is in any way involved
The code (insert into temp) suggests that you are using the typical sql server practice of populating a temporary table whose data will then, typically, be used for further processing and population of the target table.
In Oracle you rarely need to use temporary tables and when you do use them you use them differently than the way they are used in sql server.
The SQL and PL/SQL forum is the place to gets answers about tuning queries but you will get better help if you provide additional information about what you are really trying to do.
