Cs-Cart Speed : Which Version?

I have a website running with Cs-Cart 4.5

I'm thinking of making updates but as i'am actually not totally satisfied with speed, i don't want to have a slower website with a newer version.

I read 4.7.1 was slower again, is it true ?

And which version do you think is the fastest Cs-cart release ?

Thanks for help :)

There were no serious performance issues or performance updates in 4.5 - 4.10. Even though there some new features, but I do not recommend you skip the upgrade because someone wrote that it is slower. It's depend a lot on configuration of CS-Cart.

The best scenario is install demo store, upgrade it and make the performance tests. Also good hosting with Nginx, latest PHP version (not lower that php 7.1) and correct configuration will improve the performance of you store. That's for sure.
