Hi Thanks for your input. 

It is always good to receive feedback.   In my case I have the server so it is not a hosting issue in terms that I need to conform (or leave it).

So the more specific question would be starting points to try to narrow this slowdown origin.

There are many things that can be done to optimize sites, including Drupal sites.  Incorrectly configured modules, poor programming, poor module interaction, slow MYSQL server (or unoptimized).

I used Godaddy as my host for a while, but they had horribly slow Drupal sites (other sites were fine).  When I switched to BlueHost, all my performance issues vanished.  I hope that helps some.

Subject: [support] Optimizing Drupal6 + finding bottlenecks

Hi,

I have a drupal6 website that is behaving strangely with some occasional slowdowns.

Any tips while trying to identify why it is like that?

I am ruling out hardware problems or even access since other sites (not drupal based) are hosted and does not behave like that.

Under admin/reports/dblog I see lots of messages such as 

Warning: Invalid argument supplied for foreach() in webform_phone_form_alter() (line 38 of//public_html/drupal/sites/all/modules/webform_phone/webform_phone.module).

or
