["Tomohito Nakayama (JIRA)" <de...@db.apache.org>]

     [ http://issues.apache.org/jira/browse/DERBY-872?page=all ]

Tomohito Nakayama updated DERBY-872:
------------------------------------

    Attachment: TestDriver.java
                run.ksh
                file_500k.txt

I revised ClobTest program contributed by Sunitha so that we can test blob not only clob , which was tested originally.

> I think the measurement should be done in next 3 points of view at least.
> 1: Stability of performance.
> See the influence of long run.
> 2: Performance for volume.
> See the influence of size of  binary to be streamed.
> 3: Difference in type of LOB
> See the influence of type of LOB, BLOB or CLOB.
