Surprisingly, many believe that because they have unlimited space and bandwidth they’re allowed unlimited server resources as well. This is one of those little secrets within the shared web hosting industry. Server resources like number of processes allowed and memory are virtually always limited per account. Though with a few minor tweaks you may be able to squeeze a bit more blood from that shared website hosting turnip. +++ Written by Jim, Walker, HackRepair.com http://hackguard.com/how-can-i-improve-the-performance-of-my-wordpress-website

1. How Can I Improve The
Performance Of My
WordPress Website?

2. Here are a few
things I’ve learned
over the years to
improve the
performance of a
WordPress blog:

4. Unlimited shared
hosting
is “limited”
1

5. Shared Hosting
Server resources,
like number of
processes allowed
and memory, are
virtually always
limited per account.

6. So how do you
squeeze a bit
more blood from
that shared
website hosting
turnip?

7. Let’s start with
your
wp-config.php file

8. wp-config.php file
contains your
WordPress blog's
settings

9. This file governs
how your website
interacts with your
website’s
database (where
your post content
lives)

10. “Fatal error: Allowed memory
exhausted”

11. Errors like that
appear when a
plug-in begins
using up all of the
memory allocated
to your website

12. Solution
define('WP_MEMORY_LIMIT','128M');
define('WP_MAX_MEMORY_LIMIT','256M');

13. Caching is your
friend

14. Plugins that
speed up the page
loading speed

15. Plugin’s
• W3 Total Cache
• WP Super Cache
• ZenCache

16. Better leveraging browser
caching via .htaccess
## EXPIRES CACHING ##
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpg “access 1 year“
ExpiresByType image/jpeg “access 1 year“
ExpiresByType image/gif “access 1 year“
ExpiresByType image/png “access 1 year“
ExpiresByType text/css “access 1 month“
ExpiresByType application/pdf “access 1 month“
ExpiresByType text/x–javascript “access 1 month“
ExpiresByType application/x–shockwave–flash “access 1 month“
ExpiresByType image/x–icon “access 1 year“
ExpiresDefault “access 2 days“
</IfModule>
## EXPIRES CACHING ##

17. Limiting plugins
More plugins,
More complexity,
increase the
website loading
time

18. Look For Well
Rated Plugins
• Wordfence Security
• iThemes Security

19. Focus on plugins that will
help speed up your blog
• WP Smush.it makes images
smaller.
• BJ Lazy Load delays the loading
of images until actually viewed.
• Autoptimize aggregates and
minimizes JavaScript, CSS and
HTML.
• ZenCache caches content saving
reloading of content each visit.
• Server side: Batcache with
Memcached to store and serve
rendered pages.

20. The php.ini file is
simply a file used
by the web server
to control specific
options within
your account
php.ini and how
to tame it
3

21. The php.ini file
lives in your
public_html
directory

22. Edit the existing
setting or add these
lines:*
memory_limit = 128M
max_execution_time = 60

23. The bane of my
existence:
admin-ajax.php
4

24. WordPress
introduced the
WordPress
Heartbeat API back
in version 3.6

25. This was developed
to help improve
session
management, auto
saving, revision
tracking, etc.

26. Site slows to a crawl
during periods when
multiple editors are
logged into the
dashboard

27. About That
Database
5
WordPress requires
much the same
“defrag” process as
your personal
computer to keep
fresh and lively

28. • Post revisions
• Transient
records
• Trash may slow
your website to a
crawl
What Else May
Slow Your
Website?

29. WP-Optimize
• Naughty post revisions
• Trackbacks / pingbacks
• Comments in the spam queue
• Expired transient records

30. // Limit number of saved revisions to one
define('WP_POST_REVISIONS', 2);
// Empty trash every 10 days
define('EMPTY_TRASH_DAYS', 10);
Then add the below line of
code to your wp-config.php
settings file

31. Summary

32. Improve the
performance of WordPress by:
• Replacing your theme
• Deleting inactive plugins,
reducing widget usage
• Disable “Allow link notifications
from other blogs (pingbacks
and trackbacks)”
