Strange Page Loading Issue

[opwdecks]

Hello,

We have a very strange extremely slow page loading situation that I cannot figure out:

The pages that are having loading issues are all VM product pages, checkout, etc. The issue only shows when not logged in. It loads fine when user is logged into the front end.

See here for example:
http://www.restore-a-deck.com/RAD-Cleaner-Only.html

It does load fine for the home page and other non VM pages.

If we put VM shop offline it will load fine.

We have turned off/on plugins, modules, components to test with no results.

We though it might be a session issue but no problem that we can tell from the database. Restart of apache does not help.

Also everything worked okay up to a few days ago. Host has yet to respond but not sure if they can do anything or not.

Any help or suggestions on how to narrow down the cause would be extremely helpful.

my 1st question is why battle with this on a completely out of date software?

the VM2 series is on 2.6.20 now..  yours is not only out of date but completely insecure with well known security holes...

Because I have numerous custom hacks for the shipping, checkout, weights, etc that cannot be overwritten by doing a simple update. In addition the new UPS shipping module does not support Canadian UPS shipping rates and that is an issue for us. It is in the works to update.

I dont know if I would ever expect a site that has   946 lines of code in the head to be fast.


or 16,434  total lines in the html


also, why does your canonical urls redirect to another url?

do you have a 3rd party SEF you are using?

You should try vm3, really. Some of your hacks are maybe not need anylonger.

We have every intention of updating, it just cannot be done overnight as we will still have to rewrite code.

Our caching component was turned off for testing so the code is not as bad. Also does not explain why it works fine when logged in. Yes we use a SEF program but turning that off does not fix the issue.

I think it is server problem but we cannot pin it down.
