Using Project Mercury - do not see Cache Router config in settings.php

Posted by theatereleven on July 1, 2011 at 6:59am

I'm getting ready to launch a site based on Pantheon's Project Mercury, but I'm not seeing evidence that the site is using things like APC correctly.

Reading other places online, it seems that when using Memcache you have to tell Drupal to use it in settings.php with something like:

$conf['cache_inc'] = './sites/all/modules/contrib/cacherouter/cacherouter.inc';
$conf['cacherouter'] = array(
'default' => array(
'engine' => 'db',
'servers' => array(),
'shared' => TRUE,
'prefix' => '',
'path' => 'sites/default/files/filecache',

About caching for anonymous users

Posted by klaharris on July 6, 2011 at 3:44pm

I've done quite a bit of research on Drupal performance, caching, have got memcache, APC, pressflow and so on all set up but have a problem.

I have written a custom module that works similar (I would imagine) to how the flag module would (I imagine) work for logged out users, i.e. store flagging actions to the session then sync those to the user account on login or registration. Now imagine being able to see how many items you had flagged somewhere in the header, these counts are pulled from the session. For logged in users, the counts are pulled from the DB / memcache.

Moved mercury to larger Amazon image but cant get memcache working correctly

Posted by j0k3z on July 14, 2011 at 4:54pm

I've been running mercury for a year on a small amazon instance. Performance wasnt great so I decided today to move it to a large instance, which is quite a step up.

I started with a fresh Ubuntu 10.04 and installed Apache, Varnish, Memcache, etc. I moved my database over and pointed the IP at the new instance. The site shows up and Varnish is working, but no matter what url I goto it shows me the main page of my website.

Memcache and empty blocks

Posted by nublaii on July 21, 2011 at 12:32pm

We had been running a site for some time with apc+memcache+cacherouter with no problems, when we suddenly we started to get blank pages (I say suddenly because we couldn't find out exactly what was going on).

Well, not blank pages, but more like blank blocks. In the end it looked like memcache was not able to return what it was supposed to and the pages were being drawn pretty badly. Flushing all the caches fixed the issue, but only for a couple of minutes.

applying high performance tools to vps.

Posted by socialtalker on July 31, 2011 at 9:25pm

This weekend I have wiped my vps clean and am starting all over. i want to put about 18 drupal sites and a couple of wordpress sites on account. i have linode 760 plan. i want to use ubuntu 10.04 lts, i think thats what its called. i am using nginx as the server. but its so confusing trying to know the right tools to add. i believe i can add memcache on the nginx server, but how do i add varnish and apc, or do i need to add all three of those? the documents and different pages i am finding totally confusing. do i use modules to install these tools or do i do i install them at the server?

Server seems slow - where to start?

MySQL Transaction Isolation Level with InnoDB

Posted by mikeytown2 on August 3, 2011 at 8:48pm

Question:
Has anyone ran Drupal with the Transaction Isolation Level set to READ UNCOMMITTED? REPEATABLE READ is the default setting, but I think for 99% of the sites out there using dirty reads seems like it would be very helpful.

How to set this in my.conf or via SQL command:
transaction-isolation = READ-UNCOMMITTED
