// Under certain conditions in client/server mode, obtaining text values
// of CLOBs becomes very slow (e.g., it could take a minimum of 200 ms
// instead of 2 ms). If I change the column type to VARCHAR, the
// performance is very fast again.
//
// Between 2006-12-03 and 2006-12-17, you remarked: "Very large BLOB and
// CLOB data can now be used with the server and the cluster mode. The
// objects will temporarily be buffered on the client side if they are
// larger than some size (currently 64 KB)."
//
// I think the issue is now in Transfer.java, as below:
// 272: writer.flush();
// 273: writeInt(LOB_MAGIC);
//
// I believe the flush() can cause a TCP performance problem in certain
// circumstances. The reason is that when flush() occurs, the blob
// packets are flushed over the network, then a TCP ACK must be exchanged
// from client to server before the separate LOB_MAGIC packet can be sent
// from the server to client. This can cause enough latency to degrade
// application performance noticeably.
//
// I do not know of a good way to solve this, since you cannot avoid
// calling writer.flush(). One "workaround" for some applications is to
// convert CLOB to VARCHAR. However, I am currently trying something
// different. It works so far for me. My "patch" is:
//
// Transfer.java, at line 267:
// java.io.OutputStream out2 = new java.io.FilterOutputStream(out) {
// public void flush() {} };
// Writer writer = new OutputStreamWriter(out2, Constants.UTF8);
//
