Newbie question, does having a huge amount of ram on the VPS could help increase the speed of the website? the VPS is running Open Litespeed, and it has 2 vCPUs and 4096 MB on RAM, but I’m not sure if we are not using it correctly, currently the PHP Memory Limit:256M and the WordPress Max Memory limit:256M, the site it’s a bit heavy on images because it’s a website for a photographer, I was wondering if its possible to increase the ram dedicated to the site and if that will improve the loading speed?

Increasing mem limit will have a marginal (at best) effect on your pagespeed.
Especially considering that most image files aren’t executables.
It might actually harm your performance since runaway scripts which eat up memory won’t be caught as soon.
Look to more traditional methods of pagespeed optimization eg. image optimization.
My 2 cents.
4Gb is plenty for a single site. You could probably even downgrade that to 2Gb
