Never forget to backup!

A nice and easy solution which works best for me is to use sudo. This will allow to run rsync via ssh and sudo. To get it running you have to add an entry into your sudoers config file:

/etc/sudoers

backup_user ALL=(root)NOPASSWD:/usr/bin/rsync

This will allow the user backup_user to run the command rsync as root.

Next step is to add an rsync-path parameter to the remote rsync call:

rsync --rsync-path="sudo rsync" backup_user@myhosttobackup.net:/root /backup_directory

Finally rsync will automatically do an sudo to root on the remote server and all to backup all files owned by root as well.

Maybe you’ve enabled the “flash slideshow” within the Slideshow options of NextGEN gallery. This will load the JW Image Rotator on every page. I’ve disable usage of the flash slideshow by unselecting the option:

[ ] Integrate the flash based slideshow for all flash supported devices

Without usage of the flash image rotator it is still possible to use slideshows. But the overall page load time increases. For me it looks like that loading the flash object causes the overall page display to be delayed. Google Chrome seems to handle loading of the flash object faster.

Anyway for me the fastest browser available seems to be Google Chrome. On my 13″ MacBook I recognize significant performance differences when using Safari, Firefox and Chrome. That’s the reason why I’m currently using Chrome (development version) as browser.

In my case it was caused by Googles mod_pagespeed plugin for Apache. I thought this is a nice plugin, but it seems it causes to much problems with WordPress (second time here for me). So I decided to no longer use this plugin.

Add the following lines of code to the functions.php in theme directory:

function auto_login() {
  if (!is_user_logged_in()) {
  //determine WordPress user account to impersonate
  $user_login = 'guest';
 //get user's ID
  $user = get_userdatabylogin($user_login);
  $user_id = $user->ID;
  //login
  wp_set_current_user($user_id, $user_login);
  wp_set_auth_cookie($user_id);
  do_action('wp_login', $user_login);
  }
}
add_action('init', 'auto_login');

Furtunatly there is an eays way to disable the admin bar. The only thing you have to do is to add one line of code into the functions.php of your theme:

add_filter( 'show_admin_bar', '__return_false' );

And the admin bar disappears, very nice.

Delete all revision of every post. It can be achieved using a simple SQL statement:

DELETE a,b,c
FROM wp_posts a
LEFT JOIN wp_term_relationships b ON (a.ID = b.object_id)
LEFT JOIN wp_postmeta c ON (a.ID = c.post_id)
WHERE a.post_type = 'revision'

I do this from time to time. Optionally it’s possible either to disable revison managment or restrict the number of saved revisions by adding one of the following statements into your wp-config.php:

define('WP_POST_REVISIONS', false );

define('WP_POST_REVISIONS', 3);

This is nice, but WordPress does still send a few HTTP requests to netdna.yoast.com. I think it makes no sense because we have disabled the Yoast widget:

To avoid this few unneeded request I’ve installed the Yoast Remove plugin. After installing and enabling the plugin the additional HTTP requests are gone and as a result we’ve improved the load time our admin dashboard a little bit:
