This group is dedicated to solutions and approaches for high traffic, high performing Drupal sites. As such, it will deal with a lot of information around the rest of a typical Drupal "stack" -- the operating system, web server, database, and PHP tweaks that combine to support the Drupal application.
This is not a support channel or a place to post bug reports.
If you think you have found a bug, use the issue queue for the appropriate project.
If you need support, see http://drupal.org/support for options.
We are running about 50 Drupal 7 Multisites + 1 Domainaccess Site with 10 Domains on a 2x 64GB 16 Core Cluster Nodes with Apache mod_php with apc and mysql stack.
The multisites are utilizing all the same codebase and just differ in usage of content and node types.
At the moment there are 3 mysqld running on the host.
We are thinking about splitting the 50 multisites in 2 halfs and run another mysqld for that.
One of our main problems is, that deployments with changes to many features could take several hours at the moment.Read more
There is a Drupal 7 Web Application which provides personal chats, group chats, real-time polls, theater, and other activities for authorized users.
Hence, the Application contains a lot of callbacks from Front End to Back End.
I think it does not matter: They are callbacks to Drupal (https://www.drupal.org/project/js) and callbacks to node.js (https://www.drupal.org/project/nodejs).
How to test it under loading, simulating the presence of a plurality of users?Read more
In May 2017 we are hosting the European Drupal Business Days in Frankfurt and we are looking for some hight-end Drupal 8 case studies dealing with high-performance and large-scale websites.
This is the first European Drupal Business Days since Drupal 8 came out, and we can’t wait to see the newest business cases and trends.
See you!Read more
In my drupal 8 website I am facing one issue with the performance. Load test is getting failed because of too many connections comming to the database. I am having separate DB server for database.
For 500 concurrent users around 200 - 300 db connections are comming. For 1200 concurrent users around 800 - 1000 db connections.
As Drupal is a db intensive system, above mentioned counts are ok with its normal behaviour or something weird is happening in this case?Read more
I was looking to other options to move my drupal's database to some other cloud database provider like compose.com Because I am looking for a solution where I can reduce my maintenance of the whole infrastructure.
If I move my database to cloud. Does it impact on my performance?
Has anyone used these cloud database providers?
I am new to this topic. kindly advice.Read more
I am running a dynamic classified ads website on Drupal 7 and I wonder what would be the best database configuration for optimum performance.
InnoDB, or MyISAM?
What would be the best settings in my.cnf?
The hardware is a Cpanel/MySql VPS with 6 x 2.9GHz Xeon CPU Cores and 11GB Dedicated RAM.
Many thanksRead more
The core statistics module gets a lot of bad press because it triggers a db write on every page visit. But how bad is it, really? There are several functional advantages of using it...
Are there any high performance sites which actually use the module? Do you use it?
How about the Node View Count module (https://www.drupal.org/project/nodeviewcount)?Read more
Hi High Performance Gurus! Need your help since I'm kinda stuck...
I admin a Drupal 7 site on which the authenticated user base is growing rapidly.
We get about 1 million pageviews per month, and we have a target to grow to 10 million in a year and most of those hits will come from authenticated users. We're building several user-specific features such as "favorite posts", "read later", "posts from people i follow", etc. etc.
He's how we're caching things right now:
(1) Boost (for anonymous users)
(2) Memcache (as db cache)
(3) Opcache (built into PHP)
We'd like to run our Drupal 7 sites with php7. The only trouble we have so far has to do with the PECL memcache(d) extensions - no stable release supporting php7 has been published yet:
We're ll the process of moving our Drupal 7 online app platform site to a major cloud provider that will include horizontal scaling (multiple nodes for Frontend as well as multiple nodes for MariaDB). We're now considering the optimal solution to scale caching.
We are contemplating substituting standard memcache server with either internal Couchbase memcache server or Redis. The goal is to optimize performance of the site.
We are also contemplating upgrading from php v5.4 to php7.Read more
