XML file slow to load

Question

i have created a Spry Data Set from an xml file with approx. 4700 rows (not 4700 items). The problem is that it takes abourt 4/5 seconds to load when you click on the website. Is there a way i can improve the performance of this.
Also the search function performs slowly in IE but seems ok in firefox.
Can anyone suggest any way to improve the performance?
Many thanks,
Colin

Answer 1

this is the select query code:
mysql_select_db($database_myprojectbrowser, $myprojectbrowser);
$query_product_table = "SELECT projects.project_code, projects.project_name, organisations.orgranisation, projects.date_closed, heirarchy_names.description, 'products_table.php', projects.p_id FROM projects Inner Join organisations ON projects.organisationID = organisations.organisationID Inner Join project_assignments ON projects.p_id = project_assignments.p_id Inner Join heirarchy_names ON project_assignments.heirID = heirarchy_names.heirID WHERE projects.n_name =  'scotwat' GROUP BY projects.p_id ORDER BY organisations.organisationID ASC, projects.project_code ASC ";
$product_table = mysql_query($query_product_table, $myprojectbrowser) or die(mysql_error());
$row_product_table = mysql_fetch_assoc($product_table);
$totalRows_product_table = mysql_num_rows($product_table);
print json_encode($product_table);
as said above, i get an error msg
