I'm experiencing a growing performance issue on the Mail Gift Certificate panel. When I initially enter the panel it's now taking 2 1/2 minutes to bring up the entry fields.

My guess is it's related to the customer list of e-mail addresses. If I'm issuing multiple gift certificates at the same time then the subsequent refresh of the panel appears to cache the data and it comes up quickly.

Besides it being a pain to sit and wait several minutes for a panel to come up I'm concerned about future growth of my customer base and the ability to use this functionality (which I utilize a lot). I'm at 3,400 customers right now and can see that number increasing significantly over time.

As a related observation: I also have a performance issue when using the Export Email Addresses mod. It appears this may be doing the same bit of logic to create that big list of customer e-mail addresses.

I'm not certain of how to debug this type of thing for better analysis, any assistance would be appreciated!

Thank you, Kathy
