WordPress Caching Comparision – W3 Total Cache vs. WP Super Cache vs. WP Cache

Jun 11

Posted by rograndom in Updates | 5 Comments

Updated June 14. Added results for W3 Total Cache using Disk Enhanced caching only at the request of Frederick Townes, author of W3 Total Cache. I ran tests with both “gzip” and “gzip and deflate” settings.

I’ve seen a lot of discussion lately about the various WordPress caching plugins. Here’s a quick comparison using Apache Bench. First some background on the test platform.

This is a 512mb VPS from prgmr.com

Fresh install of Ubuntu 10.04

NginX, PHP, MySQL installed via APT (PHP 5.3.2-1ubuntu4.2ppa3~lucid1 (FPM/FastCGI), NginX 0.7.65, MySQL (5.1.41-3ubuntu12.3))

WordPress 2.9.2, standard Kubrick theme, nginx Compatibility plug-in installed.

Plugin Versions:

WP-Cache 2.12
WP Super Cache 0.9.9
W3 Total Cache 0.8.5.2

The following command line was used. The -c and -n flags were modified during different runs as illustrated below.

ab -k -n XXX -c XXX http://testingserver/wordpress/2010/06/hello-world/
-n flag is the total number of requests (this is 1000 unless noted)
-c flag is for the number of concurrent requests
The Results

There was no -n 10000 -c 250 run for WordPress with no cache, as it would’ve taken very long and no further information would be gained.. Updated

Remove Injected PHP code from hackers

May 21

Posted by rograndom in Updates | Comments off

Here’s a quick little php script to batch process all your .php files and remove base64_decode junk if your site has been hacked. Just save this as a php file, upload it to your website and visit that page in your web browser.

<?php
set_time_limit(0);
$tmpdir = "./";
$rmcmd = `find $tmpdir -name "*.php" -type f | xargs sed -i 's#<?php /\*\*/ eval(base64_decode(".*?>##g' 2>&1`;
echo "Finished";
?>

Lost S6E5 & E6 Thoughts

Mar 8

Posted by rograndom in Updates | Comments off

Missed a week.

Not much to think about with E5 that I can’t cover in E6 anyways.

Kate wasn’t going back to the temple the last time we saw her, with Hurley and Jack, but she ends up walking in anyways. There’s a missing part there. She’s run into someone who sent her to the temple, and not exactly to find Claire either. The top choices are either Locke, Jin or creepy jungle boy. She seems to have some knowledge of what’s going on in the end, not happy about it, but she has a new mission now.

Where the hell are Sawyer and Richard?

Are we supposed to believe that Dogen + Ash = Monster repellant? Or can Dogen fight and kill Smokey by himself, and Sayid make a hole in the ash allowing Smokey in?

Why are we avoiding the thing inside Locke’s name? “My Friend”, etc. Is it a name we already know? So strange.

Let’s jump all the way back to Season 2 when the others have Jack, Kate, Sawyer, Hurley, etc on the docks. Jack asks who they are and Ben replies “We’re the good guys.” Looking back, it’s probably true. As in they’re following Jacob and MiB is influencing the Losties making them the bad guys. If Claire is infected, then Rousseau probably was too. If you look at all of her actions, she was working towards the same end as Clarie. Blowing up the others as they came to the beach was her idea remember.
