Performance improvement

Caching would be a very nice feature, unfortunately the TSS module is in a state where I can't apply any fixes due to a CVS operational change. There is request into support to get it corrected, but I think the current work being done on Drupal6 is taking precedence at the moment.

Keep checking as there is a lot of love waiting for TSS when I can commit to the code again.

What would you cache? The core taxonomy module does static caching automatically. I would like to see the tree traversal changed so that parent/child structures don't require so many calls. However, that should wait until the module is getting attention again, as Gord says is about to happen.

Is there any benchmark stating that there is a problem performance with this module?

One thing I can see, is that this module removes the part created by the core taxonomy module and creates its own. That would be great if we can prevent the core module from creating that.

Thus, there is no evidence that TSS is a resource hog. And the way TSS works (hook_form_alter) is the Drupal way.
