Thinking about using Magento?

Ok magneto as the potential to be an excellent shopping cart. but their are some things that they need to fix.

First and most importantly is the initial page load. On average its about 250k and takes between 7-9 seconds on a broadband connection. (28 or so seconds for a 56k connection) The reason it takes so long is the javascript they use.

Second,
Seo wise it is not the best. Decent, but it needs some work

last,
If you have a lot of products, magneto is not for yo. it will take you much longer to list a product than pretty much any other shopping cart.

Also, Magento is not really free. Yes you can download and use it for free. However you can not use cheap hosting with it. The reason is the amount of load it puts on the server. If you try to use 1&1 for example, you site will take forever to load and your customer will NOT wait for it.

It's look like you are complaining that your racing car need high quiality gas

There is nothing free in this world. So in case of Magento you pay for good VPS. In case of Oscommerce you pay programmers to modify your store to run better and have all this features that Magento have.

I often see VPS servers being promoted for ecommerce websites, but truthfully, that is rarely a good solution. A VPS often has more limited server resources, considering there are typically multiple VPS' per server. Each VPS takes up a dedicated segment of server resources, and then within those limited resources, you have to have your HTTP, SQL, Email, and other service, running. That often results in barely any resources left over.

A VPS is fine if you have a small site with low traffic, but it typically can turn into a situation where shared hosting is a better solution, and a dedicated server an even better solution.

Regarding Magento's SEO solution, last I saw, they allowed multiple paths to the same page, which can result in duplicate content within your own website (not always penalized, but is something to avoid).

And yes, magento is pretty slow.

Those are all reasons why I do not use magento for serious ecommerce solutions.
