Who do you call when your Magento web store is having performance issues? You’re not alone if you said your managed service or infrastructure provider – and rightly so! (especially when a 24x7x365 service desk is there to help). Many of the calls that our partner Tenzing gets are from clients frustrated that their site is slow, and while the first step is to check for infrastructure issues, they have some other tricks up their sleeves. It turns out that, more often than not, infrastructure isn’t the issue, so they’ve put together a list of checks and recommendations to help retailers improve their Magento performance.
