InoxDesign is a fairly classic e-commerce site built on the open source CMS Magento. It is a rather good choice of technology in terms of the positioning and size of the site.
Magento is indeed one of the most advanced e-commerce CMS from a functional point of view. It offers a lot of flexibility for product catalog management, since it allows you to easily manage many products with many categories and a lot of filterable attributes if necessary.
Magento being a very popular open source CMS, it also has a very large community of developers and forums to find help.
On the other hand, to get the best out of Magento and maintain the site, it is still better to have a PHP developer (+ front!) in-house who knows a minimum about it or to go through a good web agency. Magento devs are also often a little more expensive than on other e-commerce CMS like WooCommerce or Prestashop.
NB InoxDesign currently appears to be running on Magento 1.8, is an update to version 2.0 planned for soon?
The Performance
To get an overview of the site's performance, we look at Google chinese overseas australia database PageSpeed Insight or Pingdom Website Speed Test. We will put a few representative pages of the site through the mill: homepage, category page and product sheet in particular. (edited)
Overall, the performance indicators and loading times are pretty good on these 3 types of pages, even if Google PageSpeed Insight gives (as always) lower marks on mobile than on desktop.
For example, PageSpeed Insight still indicates a few images to be optimized (size and/or compression) on product sheets like this one (these are in fact the product images in the successive steps of the “Configure your guardrail in 7 steps” module).
But overall we feel that a certain level of technical optimization has already been achieved, probably in an SEO logic. For example, InoxDesign uses dedicated subdomains (static.inoxdesign.fr and static2.inoxdesign.fr) to host its images, which allows them to be served more quickly, and uses compressed CSS files to reduce their loading weight (a very good practice).
Miscellaneous remarks
The images on the homepage load quite slowly on mobile, especially the carousel whose images are not resized on smartphones (tested on Galaxy S6).
The main menu doesn't seem very functional on iPad in horizontal position (I only tested with an emulator at the browser level). It's the desktop site menu that is displayed while it is intended to open and stay open in hover... which doesn't work very well on iPad or mobile.
There is a social sharing widget that does not work at the bottom of the product sheet sidebar (perpetual loading under Chrome). Where it is more annoying is that it also appears very visibly on the shopping cart page (see areas highlighted in yellow in the capture)!
