D7 'Aggregate and Compress CSS Files' - live site losing styles???

Posted by spessex on June 27, 2013 at 10:07am

Everytime I select 'Aggregate and Compress CSS Files' in D7 Performance settings on my live site I'm instantly losing my styles. However on my local machine this does not happen. Interestingly this only happens on my live site when I have my sub-theme of Bartik selected. If I use the default Bartik theme there is no issue. I've searched Google and found a plethora of possibilities but I still haven't found the solution. If anyone could advise it would greatly appreciated.

Thank you

Stephen

Memcached Optimization

Posted by mbopp on July 2, 2013 at 3:00pm

I have a large website that uses memcached. All users of the website are authenticated (no anonymous users). In addition to users always being authenticated, the content they see is very customized based on user (profile) fields and properties; like social media sites including facebook, linkedin, etc. Also, this site has several thousand users.

High performance comparison idea

Posted by artatac on July 3, 2013 at 9:49pm

I have been using Drupal for four years now and still find resource memory optimisation a black art. Most of my sites are low/medium traffic and low/medium complexity. I have on too many occasions struggled with sites slowing to a crawl or white screen of death and used the many suggestions of the community to try and get to the bottom of things, with varying success.

Cache overview in Drupal

Posted by jimyhuang on July 8, 2013 at 8:29am

Last weekend, I've share a slide for Drupalcamp Taipei in Taiwan.
Although I the presentation speak in Chinese, most of the slides written in English. I think this may help some people to overview cache mechanism in Drupal.

Welcome for any suggestion, comment or correct.

Thanks for this great group, when I struggle on strange performance issue, some posts give me a light when I in the dark.

Varnish to redirecting users based on their IP

Posted by pris54 on July 19, 2013 at 9:56am

Apologies in advance if this is not the best place to ask for help, I've been looking for the most relevant group and this one seems the most appropriate.

I'm trying to get Varnish to redirect users based on their IPs, for example:

1) Users with IPs from Cambodia, Indonesia, Malaysia and Thailand should be redirected to [my website]/my (this is the Malaysian version)

2) Users with IPs from Bangladesh China, Hong Kong, Japan and Singapore should be redirected to [my website]/sg

3) The rest of the IPs remain in my default site

Use Multiple Sites to Improve Drupal performance

Posted by robbin.zhao on August 3, 2013 at 2:17am

I would like to share the experience to improve the Drupal performance in here :P

as we know, NODE is the base of Drupal, therefore, the node will be the bottleneck of the system as the number of node increases. In the most cases, we have multiple node types, and also some of the contributed modules are apt to store other information into node, such as content_profile, which saves the profiles into node, taxonomy_node, which saves the terms into node, and so on. Even the worse, we have many users in system, and one user has more than one profile nodes, so it will be worse.

Slow site load help.

Posted by crisgaret on August 9, 2013 at 5:25pm

Hi guys, first time posting here after using these forums for several years with great success. I have been building Drupal sites for a couple years now, and performance has always just been okay for me. The most recent site I am working on seems to be slower to load than most. I am looking for advice on how to make this site load faster. It is not a huge and overly complex site, doesn't seem like it should be this slow.

It is the latest Drupal install, and all up to date modules. There are about 50 modules, if it helps to provide a list of those I can.

7.x modules: AdvAgg RC1 & first Imageinfo_cache dev

Posted by mikeytown2 on August 9, 2013 at 10:00pm

Last week I created the first RC-1 of AdvAgg. Has a lot of new functionality. Biggest thing if using it is the CDN module requires a patch https://drupal.org/node/1942230.

This week I created the first dev version of Imageinfo Cache. Unlike the D6 version, the D7 version will only focus on image style pre-generation as D7 fixed the performance issue in core. D7 imageinfo cache will generate the presets on file upload just like the D6 version. Comes with drush commands as well.

How would you solve this? High load.

We develop/run several sites for our clients and some of then includes live centers where users (mostly anonomous) can get live stats from current events.

For example right no we have a site(http://www.wffc2013.com/) that show live statistics from 8 different sectors(one block each, all on one page) that refreshes every 5 seconds(javascript) and where we need to geoblock on mobile devices for some visitors.

We run apache worker with fast cgi. And during peak periods we run 8 cpus cloud server with with more ram then we need so far.

Apache and APC, whats good configuration with Drupal?

Posted by Strutsagget on August 18, 2013 at 9:34am

Hi!

I'm interested in how you guys set up your Drupal servers?
We are up till now been using Apache Worker with fast CGI and adding APC. But we think we have found out that fast CGI uses different APC memory for every user, and that kind of removes some of the benefits with cacheing same data for multiple users.

What do you people use to get good performance of your Drupal sites with dynamic data (geoblocking, mobile device checking and so on) when stuff like varnish cant be used?
