ASTRAPI Posted June 2, 2016 Share Posted June 2, 2016 Quote Is there a way to check if you have Op Cache and Memcache installed on your VPS? Both are the best options to use and to verify if they are installed you can run from ssh: php -v and you should see a line related to Zend opcache: with Zend OPcache v7.0.6-dev, Copyright (c) 1999-2016, by Zend Technologies and for memcached php --ri memcached and you should see a line like: memcached support => enabled Keep in mind that this is for php support and you will need to install memcached on the system also using for Centos 7 : yum -y install memcached You can read more info about them and how they work on the official sites Enjoy !

ABGenc Posted June 2, 2016 Author Share Posted June 2, 2016 Well I have a problem. The read operations are really fast with current config but when I try to write something ( post an answer, post a new topic ) it takes longer. And added to that sometimes I get the following error (when the system tries to make REPLACE INTO, INSERT INTO ) "MySQL server has gone away" Although the server doesnt actually is not gone I suspect a timeout or a bottleneck occurs. Any specific area that I should look into ? Link to comment Share on other sites More sharing options...

Opcache is for PHP caching as far as I get but memcache is for SQL which I have not implemented yet. I test the performance differences using following site ; http://www.webpagetest.org/ Memcache didn't do anything for me, so I removed it. Host recommended OPcache over memcache anyway.

ASTRAPI Posted June 2, 2016 Share Posted June 2, 2016 Memcache don't do anything for IPB 3 but for IPB 4 is doing a lot They do different things Zend opcache and Memcache and if you use IPB 4 is good to use both. If you are on IPB 3 then zend opcache will be fine alone Link to comment Share on other sites More sharing options...

Any specific area that I should look into ? Thanks for the responses , I really appreciate I have searched the error and found out that it was caused by two parameters ; wait_timeout interactive_timeout After removing them ( which meant they were all set to default values which are both 28800 ) the error has gone away. Why this values set as around 30s caused this error is still a misery. The other thing is that I still have a small issue for posting and replying actions. They are still not as fast ( or close ) as reading the posts or making searchs. Any idea ? Link to comment Share on other sites More sharing options...

ASTRAPI Posted June 12, 2016 Share Posted June 12, 2016 TTFB will not solve any forum performance issues . You may start communicating faster but after that you should have a fast connection and close to the Geo location of your users and also optimize server tcp and kernel related settings plus caching mechanisms and a lot more....

It is doable. I have WHM/Cpanel, but I had to play around to get it installed. When I installed I had to make sure I installed it without a dependency check (now I'm thinking about that, this could have been mod_pagespeed I had an issue with on Apache2.4). This is the speeds I am getting at the moment. https://tools.pingdom.com/#!/euYQVV/http://forum.thedarkblues.co.uk However, we plan on updating to PHP 7 with fpm using MPM event.

Under the software tab, modules installers and Perl module in the software tab. Just do a search for them both. Install memcached first and then then memcache afterwards.

TDBF Posted June 13, 2016 Share Posted June 13, 2016 Install instructions for Memcached on WHM/Cpanel. https://gist.github.com/irazasyed/6066507 Then someone needs to tell me that, because I have Memcache installed on Apache 2.4, PHP 5.6 with MariaDB.
