Which online store engine is the most productive?

Question

CMS

There are a lot of questions on choosing an engine, I read them all. But there is very little about performance. Please share your experience if anyone has one.
The task is to create an online store for 100,000 products or more. I have always used virtuemart and I know it inside and out, but apparently it will not cope with so many goods. Although, again, this is not from experience, but from what I read on the Internet.
The choice is between free solutions. And it is clear that by buying a more powerful server, you can install any store, but the question here is the best performance of them and the ease of finishing. Those. it is desirable that the structure of the project itself be convenient.

Answer 1

Opencart may pull after optimization, depends on attendance. I would write a system for myself.

Answer 2

From personal experience, I can say that any free and paid one will have to be seriously finished. As soon as there were 40,000+ products on our store sites and traffic from 3,000+ per day, we immediately began to notice a decline in performance, this was especially noticeable on sites under Opencart and Shopcms. At the beginning, we coped by increasing the resources of the VPS and the channel, it helped a lot for about another six months, while the volume of stores had not yet grown.
One fairly large store is on SimplaCMS, it copes, but I feel that it also does not have a stable work for a long time.
1C Bitrix is ​​surprisingly gluttonous for hardware resources, but either we managed to set it up like that, or it’s just lucky, there are about 80 tons of goods. attendance is 5-7t., stands and works, even keeps in peaks, but the piece of iron under it puffs.
Alas, I am a project manager and I can only name the data written above, what programmers finished there, I find it difficult to say.

Answer 3

We use Opencart in large wholesale. We tried Simpla, but came to the conclusion that it is more difficult to cut it for yourself. Bitrix was rejected immediately.

Answer 4

1. In your case, of course, it is better to create your own engine.
2. Look towards Magento, it should fit.
3. I usually work with Bitrix, it will withstand 100 thousand goods without a tambourine, but the engine is gluttonous and if you plan a lot of attendance, then prepare a more powerful server.
Forget about Virtuemart for such volumes)

Answer 5

For 100 thousand products, with filters, etc. I would refuse almost all CMS and would use frameworks.

Answer 6

I worked with Bitrix and Magento with 60-100 thousand products, both ran pretty fast if they were prepared correctly.

Answer 7

A new version of ImageCMS Shop has been released . Here is the demo . They say it's not even bad.

Answer 8

As a Drupalist, I can only advise what I know. There are special assemblies - one and two . You can just put the module for Drupal. With proper tuning, it can "fly". There is also a special hosting for Drupal (http://dh.it-patrol.ru/).

Answer 9

Opencart - tested with a load of 50 requests per second - behaved perfectly, did not even lie down on an average hosting with neighbors.
For 100`000 products, the sitemap module will need to be finalized (cache)
But it will be necessary to slightly finish the caching of requests + memcached (there is a module)
Opencart lends itself quite well to finishing.
Of the big pluses, a large community and a bunch of modules for every taste (there are just a lot of them, there are also very cool ones). From myself, I’ll note - no Joomla and WP are needed. We even make business card sites on opencart, and catalogs, blogs, and even more so, not to mention stores :).

Answer 10

Praise Simpla

Answer 11

Only opencart / oxtor, preferably branches 2.3.0.2
