How much load can LiveStreet withstand?

Question

Nginx

Hello! I am creating a community on the LiveStreet engine, I am interested in the question of what load this CMS can support.
I keep everything on a bunch of Nginx + php-fpm + MySQL as a database server.
In which direction to dig, what should be done first of all - maybe something to register in the Nginx configs, maybe you know what features of this engine?
Thanks in advance for your replies. If you wish, I will give a link to my site on this engine while I am testing. Or maybe someone knows free engines with similar functionality?
