First alpha release of nodejs.module1
Just in time for Drupalcon Chicago, i've rolled the first alpha release of the nodejs.module.
http://drupal.org/node/1082646
I've put a screencast of some of the the module can do on youtube:

The module is definitely not ready for prime-time, but its getting useful enough that i need more feedback to take it to the next level.
Read moreWSOD issues and other problems with Nginx - anyone seen this before?
Hi all,
Relatively new to Nginx, got a few sites running on it, no problem - we're porting another site over but this one is doing a WSOD on any views pages (as well as Views admin) and refusing to load the Admin module or the Rubik theme. It's truly odd. Linux permissions seem ok (triple-checked), no other issues we can see. We're not getting any meaningful errors in the error log, just the white screen. We installed dtools to get more information and the errors coming back look exactly like this:

Get performance, scalability and architectural data and information
We are working on a project to consolidate several B2B web sites into 1 CMS platform. Drupal comes high on the list as functions. However, I could not find any architecture diagram, performance and scalability data/references.
Read moreMonitoring & Instrumenting Drupal Performance in Production via New Relic
Hi everyone - New Relic is here at DrupalCon and we've had a ton of conversations with folks here about drupal performance and visibility into Drupal's behavior. Dries' even mentioned it as a core pillar moving forward at his keynote. We're focused on performance and want to make sure we open up the ability for anyone in the Drupal community to sign up for our free month program. Sign up here: https://rpm.newrelic.com/signup/18 and enter the promo code "DRUPALCON" . For more information, read Dries' blog post. http://buytaert.net/playing-with-new-relic-on-acquia-hosting
Read moreMulti-colo site architecture options / example sites
Hi,
I'm an architect working on a project to rebuild our current consumer site, possibly using Drupal, and am new to Drupal and learning as much as I can as fast as I can. We currently serve all users to our site out of a single colocation (colo), but in the near future are planning to add additional colos in other geographic locations and serve the site concurrently from them all, with users being routed to the nearest colo.
Read moreAutomated performance testing for core - BOF/discussion notes
This is a summary of some of the discussions around automated performance testing of core at DrupalCon Chicago. It's incomplete, but this is a wiki so please help fill in the gaps.
Test runs
Rather than trying to integrate this with PIFR, we want to run tests against git branches triggered by git pushes. Initially this would allow for post-commit/push testing of HEAD, which would only find regressions after the fact, but from there we can extend this to forks of HEAD in sandboxes, per-issue branches etc.
Read moreAmazon s3 file serving with nginx & proxy_pass
Hello,
Problem: Drupal hosted on a VPS and files(images/css/pdfs etc) served from amazon S3
I'm aware of CDN module, but instead of rewrite urls I would like to instruct nginx to serve amazon s3 files transparently. Is it possible ?
Read moreRecommendations and Best Practices for making MySQL DB changes per tuning-primer.sh and mysql slow table log.
I am running tuning-primer.sh and mysqltuner.pl
mysqltuner.pl says:
General recommendations:
Run OPTIMIZE TABLE to defragment tables for better performance
Adjust your join queries to always utilize indexes
When making adjustments, make tmp_table_size/max_heap_table_size equal
Reduce your SELECT DISTINCT queries without LIMIT clauses
Increase table_cache gradually to avoid file descriptor limits
Variables to adjust:
join_buffer_size (> 128.0K, or always use indexes with joins)
tmp_table_size (> 50M)
max_heap_table_size (> 50M)

What else do people want to see before we start considering beta tags?
Read moreRolling Deploys
I am researching how we can build a rolling deploy architecture for Drupal. Here is the high level goal:
1) I begin a software deploy, users are not affected by this
2) Software deploy is complete, users are not affected by this
3) I switch my load balancer such that only certain networks are directed at the new code, my internal testers test. External normal users are not affected by this.
4) After verification, I open the site wider, allowing a small % of normal users into the site. Most normal external users are not affected by this.
