Description:
------------
Application server in UK
Database server in Frankfurt
If I put time logs before and after
OCIFetchStatement($stmt,$results)
 Start Time: 01.04.2009 09:28:40
 end time:01.04.2009 09:29:12 
Records fetched:1723 
30 secs to fetch from Frankfurt database.
 
The same code takes 2 secs from UK dataabse

How do I reduce the delay?

Reproduce code:
---------------
function sql_query ($conn,$sql) {
$dt =Date('d.m.Y h:i:s');	
$fh2=fopen("$_SESSION[workflow_path]temp\\Logmefuncoci.txt",'a+');
if ($fh2)
{
 fwrite($fh2,"\n 1.Sql Query: $sql \n Start Time:$dt ");
}
$stmt = OCIParse($conn, $sql);
 OCISetPrefetch($stmt,4000);   
  OCIExecute($stmt,OCI_DEFAULT);
$dt =Date('d.m.Y h:i:s');
if ($fh2) 
{
  fwrite($fh2,"\n\n2. OCIExecute end time and record count:$dt\n ");
}
//$n=OCIFetchStatement($stmt,$results);
$dt =Date('d.m.Y h:i:s');
if ($fh2)
{
fwrite($fh2,"\n\n 3. OCI fetchsatement end time:$dt ");
fwrite($fh2,"\n\n 4. Records fetched:$cnt ");
}
OCIFreeStatement($stmt);

Expected result:
----------------
time delay should be reduced

Actual result:
--------------
takes 30secs in Frakfurt database
2 secs in UK database

Same data is being fetched from both the servers
