Hi,
I run a website and have a vps server with apache. Since the traffic is high, what are best apache settings. I know it was very important to change max number of allowed connections. What are the others that might be useful to fully utilize the memory I have and deliver best user experience?
Cheers!
You haven’t mentioned what application/s you run on Apache and how many sites Apache runs. If you are like me running WordPress on Apache, I’d suggest to put Varnish (for caching) and Nginx (to server static files) in front of Apache to reduce the work load.
There are only dynamic content pages so caching would be bad. It might be similar to forum but with less sql queries and many users. Is there any advice? 
I’m sorry, I haven’t worked with any forum software. I really wished you were using some kind of blog/s. May be someone else help you with this.
It’s not a forum software but custom script a little bit similar. I thought someone might share some useful thoughts :).
