Which PHP-Framework to use for a large online store?

Question

PHP

I used OpenCart before, but when there were more than 3,500 thousand products, the site began to load too long. On the server side, everything is working fine. I decided to upgrade the store platform, but I can't choose PHP Framework for it. But I also want to choose so that I could already process more than 20,000 positions ....
What would you advise?
PS Judging by the answers to use everything goes Yii and Laravel. =)
Thanks for the answers, I will try)

Answer 1

Yes, any average framework should pull. Look towards Symfony2/Laravel/Yii2/Phalcon

Answer 2

We have 50 thousand products. 20 thousand real ones, the rest SKU
Bitrix 15
no problems

Answer 3

It's not about the framework, but how you optimize the work with the database.
I would ditch the ORM in favor of a DAO, and cache everything I can.

Answer 4

Write on Phalcon, it should be faster than everyone else, BUT keep in mind that you will develop it slower than on yii / laravel, the falcon has a lot of its own jokes, and it should not be used anywhere, but where it is really needed.

Answer 5

Optimize OpenCart. Consider a cache system

Answer 6

Laravel! :)

Answer 7

7500 articles about 50 categories, multisite everything works without problems on opencart, use caching (we have apc) and table indexes, update to the latest version in the 1.5 branch

Answer 8

Many large and well-known online stores , including the online store of the PHP developer company , are powered by Magento .
