performance

Hi!

I've promoted my new module Performance Monitor - https://www.drupal.org/project/perfmon

It has some features:
- Evaluate "Performance score" indicator using web server processing time testing with a small php script.
- System performance testing:
- CPU performance test;
- database performance test;
- file operations performance test;
- MySQL status and fine tuning recommendations.

Perhaps it will be useful to someone.

i'll be glad to see your comments and suggestions.

P.S. help me to review this module https://www.drupal.org/node/2882251

TLDR: How to take the browsers start render time to sub second levels on a mobile connection; 3.5s -> 0.9s

I've started collecting resources on Drupal performance in a "Big / Badass List"-style Github repo:

https://github.com/charginghawk/drupal-performance-resources

Mainly it addresses the lack of a performance factoid on the #drupal IRC channel. If anybody has any suggestions for good articles or blogs on Drupal performance, please let me know, or even make a pull request!

Also, I'd love to filter the Drupal Planet feed to posts on the topic of performance - if anybody has ideas on how to do this, please let me know.

Not sure where is the most appropriate post for this, let me know if anybody has suggestion.

I am having performance issues with INNODB. My major issue is that with INNODB I am getting approximately 20 times slower performance than with MyISAM. For the purpose of testing I have used Drupal 7 with devel module installed. Further more I used 2 bare bone servers with default installations so I can do parallel comparisons.

Wanted to post this here as Admin Menu is a great module! It allows your to provide quick and easy navigation to the most used parts of your Drupal administration experience. It provides cache clearing and searching and an array of other nice to haves that don't ship with the default Drupal administration menu. However due to the way that the menu needs to be kept up-to-date this module does not scale very well and can be a prime contributor to slow cache rebuilds and memory issues for larger Drupal sites.

Thanks,

ATTACHED: comparison of download waterfall before and after applying these hacks to my page.

Hi Team,

I wanted to share with you some techniques I've discovered over the last couple of days that seem to have a noticeable impact on download times. These are especially applicable to pages with large CSS files on first load, as once things get cached it doesn't make much difference.

Just a heads up that the beta 1 of the Asynchronous Prefetch Database Query Cache module https://www.drupal.org/project/apdqc is now available.

From my testing this will eliminate all deadlocks & metadata locks for all cache tables.

Hi Everyone!

I've written a PHP page that sits inside my Drupal install and is used for split second traffic processing and directing. Pending certain conditions (carried as POST data in the url) the script progressively bootstraps Drupal.

For instance we first look to see if we can direct the user to a cached page. If not, we bootstrap to DATABASE and run a couple of simple queries to see if we need to direct them to somewhere else.

Hi All!

I hope you had a wonderful holiday period :)

I've been thinking a lot about using multisite to reach the outcomes I desire in terms of performance/redundancy, and have firmed the concept up into the attached diagram.

Having never actually used multisite before I'm still coming to grips with some aspects, but as far as I can see there's no reason why I can't easily share nodes, users and sessions between the sites? Whilst allowing me to have certain modules turned on only for some subsites and not others?
