sobrenome Posted June 12, 2014 Share Posted June 12, 2014 The time to first byte in my server is about 0,4s. I want to reduce it to 0,2s. As I use cpanel, I want to keep apache and do not want to use any nginx plugin. I have read this article about disabling apache modules that are not used by many websites to make apache faster: http://haydenjames.io/strip-apache-improve-performance-memory-efficiency/ I would like to know which modules IPS needs to run, as long as my server runs only IPS. Thanks for any help. Link to comment Share on other sites More sharing options...
h-y-b-r-i-d Posted June 12, 2014 Share Posted June 12, 2014 I tried all sorts to get my TTFB down from .5 to .2 in the end SSD drives did it. Link to comment Share on other sites More sharing options...

Dmacleo Posted June 13, 2014 Share Posted June 13, 2014 better yet use cpXstack allowing you to run a site on apache OR nginx. Link to comment Share on other sites More sharing options...
sobrenome Posted June 13, 2014 Author Share Posted June 13, 2014 Run Apache with Nginx in the same server is a good ideia? I have read that Nginx is faster than Apache, but even in TTFB? What about pagespeed module plugin? If I use cpXstack I will have to install the Apache plugin or the Nginx plugin? Link to comment Share on other sites More sharing options...
Dmacleo Posted June 13, 2014 Share Posted June 13, 2014 I ran cpxstack for quite some time when I was on cpanel server. ran ip site off nginx and other domains off apache. had the h264 pseudostreaming module on both and I experimented with pagespeed but never spent a lot of time on that.

h-y-b-r-i-d Posted June 13, 2014 Share Posted June 13, 2014 Nginx looked too much of a pain to setup. I went with apache, php-fpm, unixys varnish plugin, SSD drives and xcache. Runs like a dream, sub 1 sec times and .2 TTFB. Link to comment Share on other sites More sharing options...
Grumpy Posted June 13, 2014 Share Posted June 13, 2014 Try http://www.nginxcp.com/ All you need to do is literally copy & paste 5 lines of code as root. If you really wanted, you could contract them to 1 line. :tongue: nginxcp will install nginx in front of your apache. So, it'll send php requests only to apache and handle all the static by itself. This way, you can still use .htaccess and all the apache features without having to sacrifice huge apache overhead since your usage of apache is reduced. All the whm functions like easyapache and etc are still functional. (Those will break with cpxstack) This is the easiest by far to install and you'll get to use your server in exact same manner as before. Just better performance. And yes, nginx is better for TTFB. Often by extremes. Link to comment Share on other sites More sharing options...
Dmacleo Posted June 13, 2014 Share Posted June 13, 2014 the unixy varnish plugin sucks to be honest, I bet you'll have users either logged out all the time OR find themselves suddenly logged in as someone else at some point. Unixy themselves could not fix it for me and a few others dealing with it. Had this issue both on cpanel and directadmin. if you only run forums (no ip.content as default app) I think it worked ok though. the nginx plugin grumpy mentioned alone is a heck of a lot better than that. the only difficult part (and it only takes 10 minutes) running ipboard fully on nginx (cpXstack) is setting the rewrite rules in the domain conf file. I had better performance overall using nginx with cache (I forget details now) than I did with the plugin in front of apache. however the plugin in front of apache worked better than just apache or apache with unixy plugin.

Runs like a dream, sub 1 sec times and .2 TTFB. That's amazing! I guess I will try this set up. What about the Zend Opcache (http://community.invisionpower.com/topic/399183-zend-opcache-optimizer-my-hero/)? Does it can be stacked with varnish? It takes the place of cache, right? I am on php 5.5. I guess the pagespeed module could also be stacked with all. Link to comment Share on other sites More sharing options...

I am on php 5.5. I guess the pagespeed module could also be stacked with all. zend opcache is php operation code cache. varnish is page cache. Separate layer. If you use nginx, you shouldn't use varnish as they're both webservers with capability to do page caches. (you need to write the page cache rules yourself to work well) Stacking them is counter productive. Choose one. zend opcache, apc, xcache is operation cache and you can't use multiple at the same time. They will break each other. Choose one. apc, xcache doubles as user cache (you can disable one of the features in their config), and there is also memcache for user cache. You can only use one by IPB setting. Choose one.

GreenLinks Posted June 15, 2014 Share Posted June 15, 2014 I exclude all index.php urls, admincp and profile page image uploads. That's it. And with those exclusions do you really think you are taking huge advantage of Varnish :smile: The answer is NO Link to comment Share on other sites More sharing options...
h-y-b-r-i-d Posted June 15, 2014 Share Posted June 15, 2014 I run seo URLs, so index.php is used for things like the admincp, faq, log in etc. Varnish is serving all topics, blog posts, articles - 99% of my hit content! It also includes all images, javascript and CSS. I did run tests and trials, I'm well aware what my site is and isnt serving via varnish. But do tell, i guess you must know my websites and server better than me. So errr. YES. :drool: Link to comment Share on other sites More sharing options...
sobrenome Posted June 15, 2014 Author Share Posted June 15, 2014 Is there any advantage in paying for unixys varnish pluguin for cpanel instead of installing varnish by telnet? Link to comment Share on other sites More sharing options...
Grumpy Posted June 16, 2014 Share Posted June 16, 2014 I'm not really sure why you went with varnish as a choice after most of recommendation for nginx... even with easy setup. ---------------- Unixy Varnish will make the installation easier for you. Manual varnish installation over ssh for cPanel is very time consuming and easy to make mistakes. (not telnet, at least I hope not telnet) ---------------- Overall. I do not believe varnish is a good choice for IPB. IPB offers custom response for to everyone, even guests. If they visit a page, they now must be replied with a visual feedback that the page is now read (like bolded vs not bolded). As every page request, with exception of items like css/js/images, they need a unique and tailored page. That cannot be cached. And that's the biggest bulk of the processing by significant margin. You do NOT want a cached result of one guest showing for another guest. They should be getting a different page. Varnish is very suited for pages that are consistent with regardless of who's visiting, like wordpress for example. It looks the same all the time. There are no markers for read/unread articles. IPB does. When someone makes a post, it needs to show up right away, caches built by anyone other than IPB's directive will lack accuracy since (hopefully) they'll make lot of posts fast. If it throws away a cache too often in order to make it more accurate, it'll then become inefficient. Or if you make the cache rules too lenient, you won't be hitting it often enough that there's a point to it. It'll also make skewed understanding. If you tell 99% of the site to be not-cached and 1% of the site to be cached. Of that 1% which does have caching rule, if it gets 99% hit rate, it'll say 99% hit rate. When in reality, your cache hit rate is 0.99% overall even though your directed cache hit rate is 99%. Link to comment Share on other sites More sharing options...
sobrenome Posted June 16, 2014 Author Share Posted June 16, 2014 I have many URL redirections set in Apache and I read that would be really hard to set them properly on Nginx. Link to comment Share on other sites More sharing options...
Grumpy Posted June 16, 2014 Share Posted June 16, 2014 That's why I suggested the nginx in front of apache solution. No change would be required then. Link to comment Share on other sites More sharing options...
h-y-b-r-i-d Posted June 16, 2014 Share Posted June 16, 2014 I set ttl to 15 secs for dynamic content, it takes most people that long to do a page refresh or move to another page. So far I have had no issues. Anything that needs an instant update, like changing a profile pic can be excluded. At the end of the day it works for me, my server load is zero compared to much higher before. Search traffic one hit page loads or flash social hits are no longer consuming resources.

h-y-b-r-i-d Posted June 16, 2014 Share Posted June 16, 2014 With regards database marking, guests see all the same on my setup, as I have it set to DB marking and not cookies. Members see their own set of cached results, personal to them. It's by no means ideal, but then that is not easy to do with a website that updates by the second.
