Thanks Jim, the implementation was very successful, I did it by separate the fetcher out as a new process that you mentioned as the first option.
Fetcher always fetches before main needs, then main flush fetched data from IPC.
Performance is improved by 40%.
Appreciate your help!

db2_close
DB2_CLOSE(3) 1 DB2_CLOSE(3)
db2_close - Closes a database connection
SYNOPSIS
bool db2_close (resource $connection)
DESCRIPTION
This function closes a DB2 client connection created with db2_connect(3) and returns the corresponding resources to the database server.
If you attempt to close a persistent DB2 client connection created with db2_pconnect(3), the close request is ignored and the persistent
DB2 client connection remains available for the next caller.
PARAMETERS
o $connection
- Specifies an active DB2 client connection.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
Closing a connection
The following example demonstrates a successful attempt to close a connection to an IBM DB2, Cloudscape, or Apache Derby database.
<?php
$conn = db2_connect('SAMPLE', 'db2inst1', 'ibmdb2');
$rc = db2_close($conn);
if ($rc) {
echo "Connection was successfully closed.";
}
?>
The above example will output:
Connection was successfully closed.
