Some expert opinion required on my wordpress site
i have installed one wordpress site on the smallest droplet (512MB). and going to install another application on a sub-domain. i m kinda new so have few things to clear.
Q1. my site is a very small site and i can see it consumes only around 150-200mb of ram at the moment. and i have checked my site with stress test with 250 users and still it dont take more then 10-15% of the CPU use. but i saw in some places expert recommend at least 1GB ram droplet to use when installing wordpress on it. why i m asking this is because, i dont want to change configuration once its published.
Q2. the application i m about to use on a sub-domain, will that also be include when ill take snapshot of my server?
Q3. its about zend opcache. why i need it actually? after enable zend opcache i cant see any improvement on performance. infact with zend opcache enabled, it takes more CPU usage then without zend opcache on 250 user stress test. can somebody explain it to me? is it because i m using w3tc for my wordpress?
what i can see, 10$/month is not a big deal, in comparison of the great service DO is providing. but do i really need it thats the question.
