file framework works slow

We found that file gallery and file browser browsing works exceedingly slow with a database with more than 6500 nodes (we are using Drupal 6.13 with MySql running on Ubuntu 9.10 server)

To navigate between folders can take up to several seconds (the same apply when we try to expand a file browser tree). A folder consisting of more than 100 nodes/files can already behave quite slowly.

We found a temporary solution to fix it:

first thing we commented the next line in "file_gallery.module"

$term = _file_browser_term_nodes($term, $term, NULL);
//$count_files = array_sum(array_map(create_function('$node', 'return is_object($node) && is_object($node->file) ? 1 : 0;'), $term->nodes));
$query = isset($module) ? module_invoke($module, 'file_gallery', 'query') : NULL;
We think is save our process time.

The second thing , we are not going deep into folders which we don't need. The trick is in finding just folder and files but not searching the subdirectory files an directories. For this reason we changed next in file "file_gallery.modul"

function _file_gallery_term($term, $options = array(), $filter = NULL, $module = NULL) {
//$folders = 0;
$childterms = taxonomy_get_tree($term->vid, isset($term->tid) ? $term->tid : 0, -1, NULL);
foreach ($childterms as $childterm) {
if (is_object($childterm)) {
$folders++;
if ($folders > 1) // we add this 2 lines
break; //
$term = _file_browser_term_nodes($term, $childterm, NULL);
}
}

These changes decreased our page download time from 24 second to 3secs.

Is this an acceptable solution or are you going to release a different patch?
