Ivo Pereira Posted September 5, 2015 Share Posted September 5, 2015 Hello,In the past day I have been trying to achieve an optimal configuration for my forums in a dedicated server with the following specs:Atom™ N2800 / 2 cores / 1.86 GHz+ / 2Gb RamI am using Nginx and PHP-FPM. I've tried switching from filesystem storage and database storage, along APC, XCache or Memcached.Every other options apart of the standard configuration that currently gives me an aprox. 1.7sec response time, every other option seems to be giving 2.4sec+ response time. I know of course it does add an extra overhead to the server, but shouldn't it be optimized to be fast instead of slower?Thanks Link to comment Share on other sites More sharing options...
sobrenome Posted September 7, 2015 Share Posted September 7, 2015 I think that memcached is also making my TTFB worse.... Maybe some bug after the maximum memory is reached... Link to comment Share on other sites More sharing options...

surinp3 Posted September 9, 2015 Share Posted September 9, 2015 I have a very similar thing going on. 2.5+ secs for forum index.Other parts on forum and main site (Wordpress) TTFB is about 0.2 sec and loads about 2-3 sec faster than forum index.

Rhett Posted September 9, 2015 Share Posted September 9, 2015 I'll be a little blunt here, (I hope you don't mind) you are trying to run a website with a $40.00 processor, that's not going to work too well in most cases. I would recommend that you obtain a better processor, as it's going to be your weak link no matter what config you chose to go with here. Link to comment Share on other sites More sharing options...

With separate SSD for database.And I get a slow start on forum index. Link to comment Share on other sites More sharing options...

TSP Posted September 9, 2015 Share Posted September 9, 2015 Interesting. I might try to turn off memcache tomorrow to see if it makes a difference on the page load times reported by Google Analytics. I have received some reports from staff that have noticed the community being slower overall. I'm not sure on the server specs, but it's a load balanced environment that run several communities and other sites we run with lots of visits.

TSP Posted September 9, 2015 Share Posted September 9, 2015 Not sure if related, but I'm seeing quite a lot of errors like these in my logs: [09-Sep-2015 10:27:20 UTC] PHP Warning: Unexpected character in input: ' in /.../datastore/cacheKeys.d64d66aa62.php on line 6 [09-Sep-2015 10:55:48 UTC] PHP Parse error: syntax error, unexpected end of file, expecting variable (T_VARIABLE) or heredoc end (T_END_HEREDOC) or ${ (T_DOLLAR_OPEN_CURLY_BRACES) or {$ (T_CURLY_OPEN) in /.../datastore/cacheKeys.d64d66aa62.php on line 4 [09-Sep-2015 11:05:42 UTC] PHP Parse error: syntax error, unexpected '":"' (T_CONSTANT_ENCAPSED_STRING) in /.../datastore/cacheKeys.d64d66aa62.php on line 6Do you see any errors like those?

OctoDev Posted September 9, 2015 Share Posted September 9, 2015 I have issue using zend opcache, i need to restart it constantly when installing new plugins or doing theme changes.

Ivo Pereira Posted September 14, 2015 Author Share Posted September 14, 2015 @Rhett however I can't understand why caching would add overhead to the loading time, instead of lowering it. Link to comment Share on other sites More sharing options...

TSP Posted September 15, 2015 Share Posted September 15, 2015 Have you tested?I decided I wanted a whole week with memcache before I started test without it, so I'll turn it off today. Link to comment Share on other sites More sharing options...
TSP Posted September 24, 2015 Share Posted September 24, 2015 Nothing conclusive. What I can tell for sure is that IPS 4 is considerable slower for me than IPB 3.4 was, both with and without Memcache-caching. Monday Sept 14th - Sunday Sept 20th: Memcached Monday Sept 21st - Sunday Sept 27th: No caching All of forum Just frontpage Last weeks overall Link to comment Share on other sites More sharing options...
