Hey Folks;
I've been doing a lot of performance tweaking with some of the sites I run (specifically http://latam.kaspersky.com). We have been running Varnish for some time and I recently managed to convince the powers-that-be that APC is perfectly safe and we're nuts for not running it.
Read moreHow to remove duplicate query calls?
I have a big site and recently converted to Drupal.
My forums (using drupal advanced forum) are very slow and my users are unhappy.
Installed the devel module I can see that I have a tremendous amount of duplicate queries, but how can I eliminate them?
Some queries are called over 60 times!
Devel reports:
Executed 1347 queries in 5666.48 milliseconds
Page execution time was 7213.35 ms.

Read moreAny method for clearing unused values from the 'variable' table?
After a Drupal install has been used a while, the table 'variable' overflows with values set by various disabled modules or obsolete functions which do need clearing because variable_init() (bootstrap.inc) does that unfortunate step of caching all of the table, which then often causes sites to crash due to lack of PHP memory.
Module developers may choose to use functions alternative to variable_set() and variable_get() provided by http://drupal.org/project/queryable_variables but that does not solve the pollution in all the existing 'variable' tables.
Read moreMeeting in office of gorod.ua
Yesterday I was invited to the meeting in office of Gorod.ua, the Ukrainian web portal, to speak about Drupal performance. The way like those guys are using Drupal is good, however there is lack of performance. They are spreading a spirit of their child to the whole of Ukraine, so it is a time to expect more visitors. We spoke a lot and I got better understanding of what is needed. We touched many problems, including not typical and theoretically solved them.

Read morePath_alias_cache incompatible with Pressflow external caching mode?
pressflow and varnish work best together with external caching turned on, correct?
but External caching mode skips boot and exit hooks.
However, path_alias_cache uses hook_exit to set the paths into cache.
Are these two modes incompatible?
i.e. does varnish caching with external preclude path alias caching?
If not, any ideas what I'm missing? If so, anyone have a workaround?

Hi,
I've a huge (4Go) database with 157 302 nodes and more than 1.5 million comments when the views module try to execute the query below it takes 22s to MySQL to return the result, do you have any MySQL or Drupal trick to help me reduce this time? (without using drupal cache)

Using CDN to serve Cached Site
Hi Everyone.
There are few modules, which help to serve Drupal website using CDN with Origin Pull or Push Technologies.
However, i don't want to do the things they do. They are most of the times, helping to keep the files or rich media on their cached servers, which can be used from Points of Presence of CDN provider. If we host files with them and use some URL, the files may end up hosted on some subdomain like cdn.site.com (which i don't think is good)
