Oracle Slow performance in direct mode with clob
Posted: Wed 05 Apr 2017 18:20
Oracle 12c
UniDac 6.4.16
I have a table with two clob, and some varchar fields. The clob does not contain a big amount of data, simply some text lines.
The table has 540 records.
I'm connecting to a database and executing select * from table. The time to return all records are near 15 seconds. If I execute the same query, and I exclude the clob fields, the time to load all record is less than one second.
If I connect with SQLDeveloper, for example, and I run the query, the time to load all records is less than one second.
Is there any way to improve performance loading blobs?
Thanks
