How to speed up loading of search page?

I've had some user complaints about how slow the search page is to load. I believe the biggest part of the load time is the following part of issue.search.html:

<tr tal:define="name string:custcomp;
                db_klass string:custcomp;
                db_content string:name;">
  <th>Company:</th>
  <td metal:use-macro="search_select"></td>
  <td metal:use-macro="column_input"></td>
  <td metal:use-macro="sort_input"></td>
  <td metal:use-macro="group_input"></td>
</tr>

If I remove this, load time goes from 9 seconds down to 4 seconds.That speed increase alone is probably sufficient. There are about 3,000 elements in the custcomp class. Our issue.item.html generates essentially the same list in about one second. If I replace the "search_select" line with the corresponding line from issue.item.html, the menu appears (but the form doesn't search any more!).

I'd be grateful for any ideas on how to speed this up? I'm a digest subscriber, so the favor of copying [email protected] would be appreciated (but I'll check the archives, too).

Cheers!
