Front-end tuning: downloading javascript files in paralell
I was looking for frontend tuning for faster page load. I found some very good technics, almost all already improved by drupal, but I can't figure out how to load javascripts in the button of the page. As you can see Javascript is loaded on the top of each page, while that happens page loading is blocked to other things like loading images,flash and also cause a gap while processing that code and restart loading the rest of the page...
I think these urls are good guides for improving front-end performance:

Serving flat (Varnish) pages AND allowing anonymous users to comment on content
I know anonymous traffic scales way easier than authenticated traffic -- particularly with a reverse proxy, like Varnish. But I'm wondering if the benefits are negated if you allow anonymous users to comment on and/or rate content. Anyone know about that?
I'm working on a site that has a particular (one-day) traffic spike, and am devising the gameplan on which database-intensive features to throttle and/or temporarily disable.

Measuring and improving MySQL performance over a (local) network
MySQL queries in my production environment are taking much longer than I would expect them too. The site in question is a fairly large Drupal site, with many modules installed (about 140). The webserver (Nginx) and database server (mysql) are hosted on separated machines, connected by a 100mbps LAN connection (hosted by Rackspace). Both machines are Dual Core AMD Opteron 2216HE 2.4 GHz with 4GB RAM and are running Red Hat Enterprise.
I have the exact same site running on my laptop for development. Obviously, on my laptop, the webserver and database server are on the same box.
Read moreTuning Apache for high Performance
Lately I have been trying to get my server to be better at performance. So far it has been going well, but the beast currently as many people know is apache. The server im running drupal on is only running drupal. So my goal is to trim it down as much as possible and only have the apache modules I need to run drupal. I am alternately considering installing nginx as it is much lighter than apache. I have been reading the drupal performance articles on 2bits.com and it has helped but i have not found many articles on trimming apache this much.

I was looking for an easy way to get views to pull select statements from a slave database with pressflow without having to hack the views module. I tried doing this through a hook_views_data_alter(), but that didn't seem to work.
I added another db connection to my settings.php file like so:
$db_url['default'] = "mysql://user:pass@masterdb/mydb;
$db_url['slave'] = "mysql://user:pass@slavedb/mydb;
$db_url_slave = "mysql://user:pass@slavedb/mydb;and then in a custom module I did this: (mymodule.views.inc)

Rule of Thumb for peak load benchmarking
I'm about to benchmark a site's performance under load and looking for advice on a rule of thumb for how much higher the peak traffic is than the low part of the trough.
I'm not sure if anyone has rules of thumb they've already developed, if so, great! I thought we could try to share some data points and see if there are any trends.
- The site I'm doing the benchmarking on is a fairly large site with an international appeal. It's peak hour is almost exactly double the lowest time of day.
Fast Private File Transfer using X-send file
mod_xsendfile
mod_xsendfile is a small Apache2 module that processes X-SENDFILE headers registered by the original output handler.
If it encounters the presence of such header it will discard all output and send the file specified by that header instead using Apache internals including all optimizations like caching-headers and sendfile or mmap if configured.
It is useful for processing script-output of e.g. php, perl or any cgi.

New 0.51 Mercury AMIs: Many Fixes and 64bit!
I just wanted to post an announcement that we've finally gotten out a point-update of the Project Mercury AMI. Just in case you were wondering if this project would continue, it will! I've been really excited and encouraged by all the positive feedback so far, so keep your ideas and questions coming. The 0.51-Alpha release includes a number of bugfixes and improvements, most notably it:
- Is based on the latest Pressflow including Drupal Core 6.14 and Simpletest 2.9
- Fixes the self-update process to merge correctly and pull from Pressflow's lovely new VCS home on Launchpad
- Includes the rc1 version of cacherouter
- Fixes postfix and s3 metadata issues so there's now a working MTA out of the box
Most importantly for people considering this stack for production deployments, we're now bundling 64-bit images with every release. The quickest way to find the AMIs is to keyword search for "mercury" in your favorite EC2 console. More information and AMI ids are below the fold. Let me know what you think, and what you'd like to see next!

Recommend a Xen Based VPS
Hi all,
I need to get my hands on a Xen-based VPS, that will support Ubuntu 8.04.
Preferably In Ireland [or at least Europe].
Digiweb will do Ubuntu 8.10 [even though not mentioned on their site]
http://hosting.digiweb.ie/virtual-servers/business-linux/
Slicehost are good - but in the US.
http://www.slicehost.com/our-servers/
Rimuhosting get good references.
http://rimuhosting.com
Any others - Anyone with experiences with the above, good or bad?
I always made the assumption that Latency from the US would rule out US providers.
But am I right?
Later
Alan
