Advomatic Offers Managed Pantheon Hosting
Since my very first post announcing this idea of "Project Mercury" over a year ago, we've been getting repeated questions about whether or not someone could "buy" this technology. Pantheon being an open-source project, the answer all along has been "not really."
Until today.
It brings me great pleasure to announce that my friends at Advomatic are now offering the high-performance "Mercury" stack on their existing/proven VPS hosting service. Greg and Aaron from the Pantheon team have been working with them to get it all set up, and I have to say it's looking pretty good!
There will almost certainly be more ways to get Pantheon hosting in time, but it's really exciting to have our first go-to provider, and I couldn't be more pleased to have that partner be Avomatic. I've deployed many clients with them over the past four years, and I trust their team to do an excellent job on the sysadmin front. They offer 24X7 support, 100% network uptime SLA's, and flexible hosting plans. So, if you've been watching the progress here, and waiting for an option to run Pantheon without having to go it alone, get in touch with Advomatic and see for yourself what all the fuss is about.

Getting a handle on all this good information
I've been following this group for a few weeks now, and it is an excellent source for information on boosting Drupal performance. The contributors, especially regular contributors, do a great service with their efforts.
One thing I find daunting, however, is that someone new to this topic can be overwhelmed by the breadth and depth of the information. Of course, that is more a good thing than a bad thing because we should all rather have too much info rather than too little info.
Read moreMoving GZIP compression from "in-front" of to "behind" Varnish cache -- optimal config?
I currently have an Nginx (SSL,GZIP) -> Varnish -> Pressflow/Apache setup (more detail config @ bottom)
Atm, all GZIP compression is done @edge by Nginx.
Varnish caches UN-gzip'd content, and Nginx GZIPs at every request.
Couple of questions aimed at further improving caching/compression performance:
(1) Iiuc, if I move GZIP'ing to Apache, Varnish will cache GZIP'd content ... removing the gzip-at-every-request load.
True?
(2) It seems I've got 2 options for GZIP'ing @ the backend --either in/via Apache mod_deflate, or using Drupal's Performance config, i.e.,

Multiple Varnish Servers
Hi All,
I would appreciate some discussion/input regarding running with multiple varnish servers. We host a bunch of site on AWS, some of them are reasonably high traffic, and are integrating Varnish into our setup. We are currently considering 2 different configuration models: Option A: run with 2x Varnish frontend servers, passing off to the required backend servers; and: Option B: have each Drupal server with a dedicated Varnish machine (Mercury-type setup)...
Read moreComments not showing on node page - due to caching?
I've encountered the following issue: Actually, all comments showed up on the node page. Out of a sudden one of our users reported that there are no comments anymore. Indeed she was right. I had a look in the database and all comments were there. I looked under the admin/content/comments page and could see all comments. They just did not show up on the node page.
Read moreDon't know what to do with Devel output
Hello all,
I've recently uploaded my portfolio-website but the website goes really slow... The transition between the pages sometimes takes about 4-10 seconds...
(My hosting provider is Servage.net).
This is what I already did.
- Installed Boost
- Caching mode: normal
- Page Compression (boost & core): enabled
- Block Cache: enabled
I've installed Devel to see what's going on, but I don't really know what to do with the output info.
Thanks a lot,
Greetings. Bob.

Views pager for sites with large datasets
One of the newspaper sites I work on has several hundred thousand nodes of content. Because of the fairly large dataset, Drupal's core paging system can take several seconds just to run the count query required to return the total number of pages in a list of content. As a solution, I created a simple module to solve this problem for Views pagers. The module adds an additional pager option called "Lite" that produces a simple pager without executing the expensive COUNT query required by the default pager.

Compiled C code as PHP library of Drupal functions for performance
I swear I saw that someone had created a project page on Drupal.org for a php library that pushed a lot of Drupal's functions to native C code.
Now I can't seem to find it and I didn't see any discussion about it recently in this group.
So: does anyone remember what it's called and where it is?
Also, has anyone tried it? Did you like it?
Read moreSame DB server with more RAM or Dedicated DB server OVER database latency.
Hello Team,
I have heard about database latency, when we have a seperate DB server. But a lot of people are using them nevertheless.
We can also have a single server with 16 GB or More then that RAM.
Some says dedicated server are always good some says more RAM on same server, I am confused.
Which one would be better? Please suggest.
Thank You.
