performance

Why?

The first idea that came to my mind when I first ran cache clear that lasted a minute or so, was "I want it run quicker!". If you are those unhappy guys who don't have an SSD, but do have a bit of RAM - you may find this discussion interesting and useful.

I've been having serious performance issues with D7 on a shared host.

I've searched around and read loads of articles and opinions about this but at this stage I've got myself in a muddle and I'm not sure what to do next, hence the call for help.

I'm hosting a fairly complicated site on 5quid host in Edinburgh. They do not have any opcode cache, no memcache and no varnish. Since this is shared hosting I don't have the option of adding these things.

In Drupal 7, i have found that CLEAR CACHE (on the Web Panel) is using extreme high Memory resource. Giant projects like mine, needs over 350MB to that process.

• Then i set 400MB inside php.ini

So as far as i have investigated, i have found that having high memory limit (Globally) is totally the damage to the overall Performance because every single script is using that limit in memory.

Je propose d'organiser un meetup drupal sur la thématique de la
performance en drupal.

L'idée de base c'est de faire de ce meetup une partage d'expériences
et astuces. Comme faire drupal marcher vite. Soit du point de vue du
frontend, soit du point de vue backend, du serveur HTTP jusqu'à la
base de données.

On invitera des personnes qui sont liées à des sites drupal à fort
trafique pour parler des stratégies employées pour régler le problème.

Il y a de l'ouverture pour parler de nouvelles approches, en dehors
des sentiers battus.

I'm trying to speed up my website and need some suggestions about what things go together and which typically give you the most performance increase. I need to lower CPU usage and caching seems like the way to go. We really need to decrease CPU because our host (a pretty well respected and expensive VPS) is being overloaded with only 2-3 simultaneous users. I've run Yslow and the developers are working on making the recommended changes there.

I am wondering what tuning and configuration do you do to make your environment faster?

Here is my experience:

1. Got more memory utilization from installing PAE on 32 bit Linux.
2. Installed APC, tuned MySQL and got about 50-100% performance boost. See my blog post for more details: http://vmirgorod.name/blog/boosted-lamp-drupal-devs
3. Realized that new NetBeans 7.1.2 is working much faster then Komodo IDE, Zend Studio or Eclipse. People says that 7.2 RC are even more faster. Checkout here http://www.netbeans.com/downloads/index.html

Hello!

Having a pretty old laptop as my primary development workstation, I'm very concerned about development speed. Under development process I mean the most frequent operations you do when making a website, like:

• installing and configuring modules
• creating and configuring entities (nodes, products) and fields
• theme development

I'm pretty excited about some recent developments I've recently done in the HTTP Parallel Request Library. Thread that has all the dev info: http://drupal.org/node/1427958

You can now issue a callback in the event loop (just like node.js) so while your function callback is running, I/O is still going on in the background (http requests currently), filling up buffers waiting to be read after the callback is done executing.

Hi,

I am a drupal developer , I used to create thumbnails for the uploaded images via Image cache actions in drupal 7.0 it takes about 100% CPU utilization. I use amazon EC2 with m1.small as my server and stored images in amazon s3 bucket, but i am creating the thumbnails in my EC2 server and then pushing to S3 via cron job, i also tried creating thumbnails using normal PHP (using imagecreatefromjpeg() and imagejpeg() functions) and setting it as a cron job for every 5min ..
, which also takes around 100% of cpu.

I tried to increase the "apc.shm_size" in php.ini
but no improvements.

Em chào các anh,

Em là sinh viên năm cuối của trường đại học Công nghệ. Hiện tại em đang làm luận văn về "Evaluating Drupal Performance". Em xin các anh một vài gợi ý cho bài luận văn của em với ạ.

Hiện tại em có tạo 1 trang drupal và joomla có chức năng giống nhau (em cố gắng cho 2 trang giống nhau nhất có thể, cùng có login, recent content ...ở vị trí giống nhau)
