External Table Load Very Slow

Dear Experts,

We are using External Tables to load CSV files to Oracle Database  (Oracle 11gR2) on Windows 2008 R2. However, while average load time was 15-20 seconds previously, nowadays it takes even up to 15-20 minutes. The average size of CSV files did not change.

What can be the problem or what can I do to trace the problem?

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

What do you mean with "previously"?! Did something change in between?! New hardware, other OS etc...?!
To track the mentioned latency, you could do a session specific trace for that loading and tkprof the results afterwards. Then you might see where this process needs to be tuned or bug-fixed...

check the wait events while the load is running.  Ideally you could compare these to activity of old runs that were successful.
