Slickgrid optimization recommendations?

Posted by Ari Gold on April 25, 2012 at 8:11pm

I'm using d.o/project/slickgrid and used devel generate to add 1000 nodes, and some exposed filters. The filters work quite fast when searching for a specific string, but when I "reset" to load the entire slickgrid again, it takes about 30 seconds to load. Any suggestions on how to optimize so it loads quicker?

Can page cache be configured to ignore certain query parameters?

Posted by scottatdrake on April 25, 2012 at 9:33pm

When our newsletters go out, links are appended with user-unique tags for tracking purposes and whatnot. Something like example.com/page?userID=1234. It is my understanding that these unique values are all treated as unique pages and effectively bust the cache.

We experience big spikes in web server and database load as soon as these newsletters are sent out. Is there any way to keep those queries in the url, but have the caching mechanism ignore specific ones?

I feel like someone must have run into this before, but my google-fu is coming up short.

Short discussion about APC user cache vs Redis vs Memcached vs... whatever clone

Posted by playfulwolf on April 26, 2012 at 11:03pm

Hi,

Why there are so many installations and topics about memcache/redis and clones for Drupal instead of using APC user cache (not opcode)
I see the benefits in those scenarios:
1. Multi-server instalations
2. PHP configurations, where multiple threads/processes cannot share common APC user cache

What I haven't experienced:
1. Memecache is faster that APC - wrong! It is slower. Do simple tests and see, that it is 10-30% slower

Hi,

I'm in the process of building a linode 512 nginx-based server, and am in need of advice. My end goal is for the server to host a number of course sites for college writing courses. The sites are drupal 7 based, and use a decent number of modules:

Chaos Tools
Panels
Views
Workflow
Editable Fields
Private Messaging
Organic Groups
Heirarchical Select
Entity
Token
Menu Token
Switchtheme
Webform
Date
Calendar

Scaling Question

Posted by Vidus on May 2, 2012 at 2:02am

Hi,

I had a question on scaling and I wasn't sure about the specifics of it to Drupal, and thought this would be the best place to ask.

Currently, my workplace is running Drupal 6/7 sites on a 2gb server (1700 actual available).

I was wondering what the differences in performance would be if we split to two 1gb servers, with one handling the files and the other handling the databases.

We have around 100-120 sites that are being used on a regular basis, though only a few of the sites deal with even vaguely heavy traffic.

Varnish3 + Drupal7 + Nginx with Multiple sites

Posted by Baber Javed on May 3, 2012 at 11:04am

I've been trying out several VCL files across the web but my problem seems to be a bit different. I have several websites (Rails + PHP) running on my server on Nginx + PHP-FDM on port 80 and I need to setup Varnish for one of my Drupal websites only so I obviously cannot change the port 80 to be used by Varnish as all the other sites will go down as well.
Any Ideas what my VCL file should look like in this case? (PHP-FDM is running on port 9000)

Pressflow with HipHop for PHP

Posted by michee.lengronne on May 9, 2012 at 11:19am

IS there a way to compile Pressflow with HipHop for PHP ?

I would like the most performant Drupal because I have to enable a lot of modules in it (when I say a lot, my modules folder contains currently 333 projects), and the site will have to handle with a huge number of users and contents.

Varnish 3 can't cache, all MISSed. Using Drupal 7

Posted by gilzero on May 10, 2012 at 3:47pm

Hello

My stack:
- Ubuntu / LAMP
- Drupal 7.14
- Varnish 3.0.2
- HTTP port 8080 / varnishd port 80

varnishd is running in front of backserver.

Basically, X-Varnish-Cache = MISS in header for ALL the pages, not caching anything at all.

I also tested in http://www.isvarnishworking.com , the result confirmed, please see my screenshot below
