Views: "I have a hammer and everything else is a nail"
I am going to intensively use the chapter 5 of the Anti Pattern book on the Golden Hammer because it is exactly what views is. Putting it in core would be in my opinion a big mistake. I will explain first what is the problems of this anti pattern, and why the "in core" wont magically solves all the code and management issues whereas the general solution should be: expand your horizons.

Hoping for some feedback on improving my site's performance
I hope I'm posting this in the proper place.
A client of mine is running Drupal 6 on IIS7, and has started getting more traffic (about 6000 hits/day, 98% anonymous) resulting in server CPU (2GHz Xeon) being completely maxed.
I'm trying to find the bottleneck, and I've stumbled on something which I'm not sure what to make of: In trying to debug Boost's performance on this server I inserted a watchdog notice in hook_init() and found that any page load can fire hook_init() as many as 20 or 30 times.
Read moreSite Performance Suggestions
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 utilizing the flag module on a site for multiple purposes; bookmarks, likes, favorites etc. Because flags are stored directly into the database I am a bit worried about running down the database. Is it possible to store flags in memcache or similar and then process them on cron?(as the VotingAPI allows). Any suggestions welcome.
Note: I am planing to run Varnish with ESI(loggedin users), memcache, nginx and CDN. Also I considering using Disqus module for comments (to help offload the database).

Getting "Secure Pages" like behavior behind Varnish or AWS ELBs
I have a site that has both a large anonymous-use and logged-in participant usage. In an older version, the client used Secure Pages to get some pages into SSL, but to force most traffic back into regular HTTP if the page did not require it.
How best to implement this with Varnish or AWS?

Force Views ajax paging to use GET instead of POST so it can be cached.
After witnessing some dramatic CPU spikes, I've discovered that Views' ajax paging sends requests via POST instead of GET (very large POSTs!), preventing them from being cached by Varnish and the like.
Evidently, I'm not the only one that has encountered this but I haven't found any solutions.
Any ideas?
Read moreMultiple webserver access same file at the same time?
Hi all,
I am setting up a website with Drupal 7. In plan, I will have Varnish+HAproxy+Drupal7+memcached+mysql+nfs. Here I have a question that if I have 2 webservers running same drupal, what will happen if the 2 webserver write the same file or same database entry? Is there anything I could do to avoid such situation? Or if drupal itself has mechanism to avoid it? Is Mysql Cluster or Glusterfs could help on such situation?
I am not sure if this is the right place for the question. If not, please point me the right place.
Thanks a lot.
