[Zope] optimize old code

[Yuri]

Hi!

 I've an old product, based on zclass and zope 2.6, I would like to 
optimize (as possibile) the insert and cataloging of a zclass.

 Now I use this scripts:

form that creates the request ->

--
<dtml-let ut="_.SecurityGetUser().getUserName()">
<dtml-with "manage_addProduct['Dafne']">
 <dtml-with "dafne_item_add(_.None,_,NoRedir=1)">
 </dtml-with>
</dtml-with>
</dtml-let>


--


<dtml-with "dafne_item.createInObjectManager(REQUEST['identificativo'], 
REQUEST)"> <- just set an id for the class

<dtml-call 
"propertysheets.metadati.manage_editProperties(                 
REQUEST)"> <- edit properties

<dtml-call "manage_permission('Cambia il contenuto dei 
dafne',('Manager','Owner',),acquire=0)"> <- set permission and roles

<dtml-call "manage_addLocalGroupRoles(ut,['guardone'],REQUEST)">

<dtml-if expr="pubblici == '1'"> <- anonymous can view?

 <dtml-call "manage_permission('View',('Anonymous',),acquire=0)">

<dtml-else>

 <dtml-call 
"manage_permission('View',('Manager','Owner','guardone',),acquire=0)">

</dtml-if>

<dtml-call "manage_permission('Change Images and 
Files',('Manager','Owner'),acquire=0)">
<dtml-call "manage_permission('Add Documents, Images, and 
Files',('Manager','Owner',),acquire=0)">
<dtml-call "manage_permission('Add 
ExtFiles',('Manager','Owner',),acquire=0)">
<dtml-call "manage_permission('Change 
ExtFile/ExtImage',('Manager','Owner'),acquire=0)">

* Can optimize here? *
<dtml-call unindex_object> <- my catalog is not called Catalog but 
catalog, so I've read I've to do this three steps
<dtml-call "manage_editCataloger('catalog', REQUEST)">
<dtml-var  index_object>
* *
</dtml-with>

* do redirecting*
<dtml-comment> Now we need to return something.  We do this via
                a redirect so that the URL is correct.

                Unfortunately, the way we do this depends on
                whether we live in a product or in a class.
                If we live in a product, we need to use DestinationURL
                to decide where to go. If we live in a class,
                DestinationURL won't be available, so we use URL2.
</dtml-comment>

<dtml-if NoRedir>
 <dtml-else>
  <dtml-if DestinationURL>

   <dtml-call "RESPONSE.redirect(
       DestinationURL+'/manage_workspace')">

  <dtml-else>

    <dtml-call "RESPONSE.redirect(
           URL2+'/manage_workspace')">
 </dtml-if>
</dtml-if>

 Any idea? TIA!
