We have a dedicated server through fasthosts and are running 1 wordpress set up and a multi-store magento set up.

Our Magento sites are running at a slow speed back and front-end compared to the wordpress site.

Has anyone had experience of optimising a dedicated server for Magento?

I've posted our server spec below along with our configurations for php and my.cnf. We've followed some advice on tweaking the settings but things don't seem to be running any better.

As you can see we're not on a small server set up so we believe we should be getting better performance from it.

Can anyone see anything that we are doing wrong with the set up?

how many stores are currently setup? – Mike Sep 21 '11 at 11:56
1 base store and 12 stores from that although there is no product on the majority of them at the moment. – Vince Pettit Sep 21 '11 at 12:09

So here is the issue with magento and multiple stores from what I found.

Magento does not scale with multiple stores. I was at a ecommerce startup that tried using magento to give bloggers shops. We used magento's multi-store of course. So the issue is each item that gets added to a store gets added to all the stores. Magento's DB model is good for making it very flexible but doesn't scale well when you have multiple stores. We had around 100 stores at the time with 5x the server power of you and adding a single product took 90 seconds.

This caused all sorts of things to be slow like checkout. So yes your server configs are ok and all but it's a magento problem.

We looked at queries that were run and some of them were 9 pages long for checkout and to add a product.

Sorry I don't have much help.. but my advice is to dump magento asap and find another solution.
