  • Could not use Memcached on vB4 by installed 2 caching systems in a VPS?

    Hello,

    I have just moved my web hosting forum to a new VPS and I installed Varnish cache on it

    After that, I install Memcached to enable vBulletin use with Memcached but the forum was error immediately.

    For previous forums or last time I could use Memcached with my forums but this time it is impossible.

    My questions is, does they conflict together? Should I remove Varnish and just only use Memcached? but the problem, my web hosting control supported Varnish.

    Please share your advice.

    Thanks

    While properly configured, they should work together. However, we don't recommend using Varnish with vBulletin. We had it installed on our servers and it constantly caused caching errors. Now we bypass vBulletin at all times. Varnish is designed for pages that are more static.

      Cool, really a great share about experience using Varnish with vBulletin, I will note this to avoid use Varnish on my vBulletin forums

      What about OPcache ? Do you know about this caching system? can I use it with memcached for my forum?

      Honestly I just want to improve performance for my hosting and speed up vB forums to have better loading speed.

      Thanks

        OPCache, the built in PHP 5.5 caching? I don't foresee any problems. However, we do not provide explicit support for it in vBulletin.

        You've switched vBulletin's caching to memcache in the /includes/config.php? You're storing attachments, avatars, and CSS in the file system?

          Of course I enabled memcache in config.php and running it on my forum, also storing attachments, avatars, and CSS in the file system

          I saw my forum improved performance since activated these factors. May I will try to install OPcache on my hosting to test it.

            You can switch many tables to INNODB in vBulletin 4.X to get additional performance and reduce table locks. Basically anything without a fulltext index unless your using MySQL 5.6 or higher.

            PHP and MySQL versions provide significant performance benefits. PHP 5.5 and MySQL 5.5 significantly improved performance. If vBulletin 4 is updated to support PHP 7,that is another performance boost.

              Could you refer link for the tutorial to switch tables into INNODB in vBulletin?

              Basically, I need a guide to optimize table or Mysql to reduce loadings on queries. Install Memcached and Memcached for PHP can improve performance?

                  Just curious why vB team didn't update these into latest versions of vB forums?

                  When a user edits or changes data type or codes then the changes can be lose when they update versions and can get errors/conflicts...etc.

                    vBulletin 5 installs and updates with INNODB tables. vBulletin 4 is not under full development.

                      Thanks Wayne but it is not fair for users that using vB 3 or vB4 versions. All are paying for same price to use vB cms but getting the support different between vB versions.

                        Your license gives access to vBulletin 5. It isn't really about support level. It is about development and what the versions are designed to support. When vBulletin 3 and 4 were developed, there were a lot of problems with INNODB that the average user couldn't support. As such, it was decided not to use INNODB as the default installer. Now many years later, INNODB is the MySQL default table engine so it is more widely supported.

                        You can convert most of your tables to INNODB in vBulletin 4 without issue. Most likely in vBulletin 3 as well. However, we haven't tested vBulletin 3 under that scenario.
