Can JDBC Oracle file stream blob inserts be speeded up?

I have these four different ways by which I am inserting some file data into an Oracle database using JDBC and PreparedStatements. - **Approach A** ps.setBytes(1, fileDataInByteArray); - **Approach B** Blob blob = ps.getConnection().createBlob(); blob.setBytes(1, fileDataInByteArray); ps.setBlob(1, blob); - **Approach C** ps.setBinaryStream(1, fileDataAsInputStream); - **Approach D** ps.setBlob(1, fileDataAsInputStream); In general, Approach C & D seem to be very useful for large fileData. A & B can run out of memory, but obviously C & D are more reliable. However, when the file size is smaller the danger of OOM is not there. I find that A & B take less time for the database insert. I suppose that’s because when the data is a byteArray, it’s much faster. What can I do to speed up the insert when using C&D? I have tried wrapping the input stream with a BufferedInputSteam. I played around with the buffer size. But that did not help. Are we at the mercy of how fast Oracle can read the data? Can that be speeded up?
